View Full Version : Bosch Part No. for FUEL PUMPS

Guys,

I did alot of research b4 I purchased my pump and I figured you'd all be interedted in knowing certain particulars.

Here goes.... The following are all Bosch Part numbers for various pumps with different flow rates.

Bosch Motorsport Pump (Popular Choice Apparently)
Part No. 0580 254 044 -
228 litres per hour @ 5 bar/75psi

Universal High Pressure Pump -
Part No. 0580 254 053bat
228 litres per hour @ 5 bar/75psi

Part No. 0580 254 023
210 litres per hour @ 6.5 to 8 bar/100psi

Part No. B261205413
220 litre per hour @ 10 bar/150psi

Part No. 0580 254 019
167 litres per hour @6.5 bar/

Correct me if I'm wrong guys, but doesnt the standard S13CA18DET regulator regulate pressure to 36psi any. So I figure and of these will do. ALl depends on the size of em.

I don't know the part numbers used by SE-Nissan or Norris, but I just purchased and fitted a pump provided by SEParts (Nissan Specialists) and their Bosch Part number is

Part Number 0580 254 040.

I remeber speaking with Bosch Engineers on the phone and they didnt quote me this on for some reason.

However, I'v fitted it and the car runs 10 times better. No flat spots, nothing. Just pure PULL especially around up to. The engine seem to want to rev out more (which is always a good thing)

Obviously these performance specialist must test these products on the engine to determine which is suitable for ones needs.

It might be that a £50 cossi pump might me good but then it may not be consistent for the Ca OR sr LUMP, otherwise we'd all use it.

When Speaking with Nana @ Options Motorsport (this guy is quite expensive but after long conversations is blatently obvious he knows his stuff) I was speaking to him about pumps.

HE straight away said HKS (being a Jap of course) but when I said I had 300zxtt pump he said NO, dont fit it. and dont fit an Escort Cossie pump either.

As you can see from the Bosch list above all these pumps have different pressures, and these could maybe have an effect on an engines performance wich explains why it might not be wise to fit certain types.

I'm no expert at this subject which is why I wanted to delve into it a little more, for my own knowledge and my Bank Balance.

It might b that some of u use Cossie pumps and the car runs fine, Great!

Its personal prefence really at the end of the day. Nevertheless, I hope those of you looking to buy an uprated fuel pump find the above information useful.

Over and out!

So, Steve, you've fitted a new bosch pump with Part Number 0580 254 040 - correct?

did it fit easily? any probs at all. Im thinking of getting one.

If anyone is after fuel system parts try www.fuel-parts.co.uk (http://www.fuel-parts.co.uk) they're really good. I got a new lambda sensor from them a while ago. Excellent service...

Yeah, no probs at all.

had to modify the bracket a little but other than that it fitted fine.

The car pulls much more smoothly and seems to want to rev out more. Probably shows how much the car was massively underfuelling.

Recommend it. I dunno about the others but the pump I have is supposed to flow 170/180litrs per hour at 125psi. So the pressure is more than enough. It sounds a little louder too. You har the fuel pumping through quite a bit.

But yeah, get onr. Good for 400bhp+

SteveSadler, apart from the mounting braket is there anything esle I have to modify to fit the pump?

Cheers mate

Im running a Cossie pump on mine. Its fairly straight forward. There is like a rubber holder in the bottom of the pump harness, this will either need removing or a hole cutting in it, the feed pipe from pump to engine needs a little bending, and maybe chopping so that a hose can fit on it OK. Also the connections on the fuel pumps are different, though that bit is dead easy, just crimp a new connector on the end.
To hold the pump in place, I just used a couple of zip ties to hold it against the pump harness, so far Ive had no problems http://300zx.co.uk/200sx/ubb/biggrin.gif

Hope it helps

Lemmy double double check this just incase any of you are watching.

Part number 0580 254 040 Is the one I want?
I just rang fuelparts off jez's link and it seems to be mega cheap - If thats the one that SE provide then I guess it must work fine, and be a doddle to fit.

True/False?

I can have one here by monday if its the right one. Cheers for help.

Paul_S13

15-06-2001, 15:38

The way I see it is.....if a cossie 4x4 has 220bhp standard then a fuel pump from one of them will be fine, I heard there good for well over 300bhp!

SteveSadler

15-06-2001, 16:13

Paul I just had my car RR this afternoon @ PE with the pump I specified at the head of this topic.

The car ran fine, if anything its now a little too rich @ top end.

Its clear that I'm definitely not leaning out.

With a T28 I will make major HP the guys said. The car is set up perfectly and since fitting the FMIC and Group A Pump and Clutch the torque has shot up right across the rev range. In some cases there is a 35Ib/ft increase.

peak power is early now -due to Turbo being in sufficient to provide enough Air at Higher RPM.

When the T28 is in and running it should be pushing around a tru 270bhp mark due to slight overfueling @ top end.

Cant wait now.

forgive me for asking a weird question, but whats all this about it not sucking fuel if you got less than 1/4 of a tank? I dont much like the sound of that. Are they all like that? I dont remember having mine over 1/4, ever.

Paul_S13

15-06-2001, 22:04

The replacement pumps sit higher than the standard items so the do not sit as low down in the tank hence the problem of fuel supply when you corner hard.

Stevecarter200

16-06-2001, 09:21

Chimp, the fuel pump that SE supply isnt a Bosch item. Its made by Walbro. I think the model number was 242. It flows 190 l/hr and cost £180 from SE. After reading this thread and having already fitted the pump (and found out how easy it was) I wish Id gone elsewhere to buy one. Would have saved myself about £100.

Liekwise m8.

Well, all in a good cause.
u guys have save me a few pennies with hints n tips, so its only fair i do the same.

everyone should contribute.

I also found out that adjustable actuators from Fords Escort Cossies (l8tr versions) fit Nissan T25's as they also ran the same Turbo

And I even think there available for 40-50quid.

How much does Norris sell them for? i heard its about 125-130quid? correct me if I'm wrong.

So I reckon my actuator is a little week as its not holding boost very well.

So I'm gonna investigate this avenue a little further.

Of course, any hints n tips will be welcome

I remember reading up about walboro pumps from a company in the states and they only quoted me around £40 quid. That was for the SR20DET but could garauntee it would work with the CA lump as he didnt know much about this.

Steve Sadler,
First thing thanks for the info on Bosch pumps.I have now got the 0580 254 040 as recommended in my car.Works great with no flat spots ,but when I open the filler cap it doesn't hiss like it used to!A small point I know but none the less worrying.Does this happen wtih yours?

Car pulls better. However, it is very noisy
at idle in the cabin. Its like sitting in a Jumbo at 30,000 ft. Dont notice it at normal road speeds but annoying all the same.

Anyone else notice this.

When Steve Sadler and I fitted his uprated pump we found that the large O ring that fits between the tank and the top of the pump assembly had somehow expanded and did not fit into the groove around the top of the tank.

To get it fitted we cut about 5mm out of the ring so it would seat in the groove. Having looked at the workshop manual, it says that the O ring is a discardable item.

I would suggest buying a new O ring (can't be more than a coupe of quid) and refitting the fuel pump assembly.

SteveSadler

11-07-2001, 13:35

Yeah,

they doo hiss alot @ idle. thats normal for the pressure.

That particular part number I quoted you is a GROUP A Spec Pump

170litres per hour but @ 125psi

Which is why its noisy.

Will give enough fuel for 420bhp.

Thanks for the replies, I'm off to Nissan tomorrow to get a new 'O' ring thingie.

I must say a big THANK YOU to Steve Sadler for all this information, the difference in the car is unreal. This may sound a bit poofy but the car is tons smoother off boost now and so much easier to drive round town.On boost it seem's alot more responsive and eager to rev and rev and rev http://300zx.co.uk/200sx/ubb/smile.gif

So the general consensus is which pump then ? ?

Escort cossie
Bosch 0580 254 040
Walboro

If a different fuel pump is fitted does the engine need setting up in any way or is it just a simple case of swapping old for new ?

SteveSadler

Cheers Dave,
and Jeffers. in answer to your question no. You dont need to do any setting up. By all means go for a RR to check fuelling. But you'll find it will be ok as your fuel pressure regulator (at the end of the fuel rale towards the rear left side of the engine) regulates the amount of fuel to the injectors anyway.

You should have no flat spots no.

And the pump I used is as I quoted - the bosch one. Its a group A pump providing enough pressure at a reasonably enough litres per hour for 420bhp.

And personally , 420 bhp is enough for any S13 owner.

If it aint then ya better off buying a 300zx, R32,33,34 or even 35 (next year when they come out)

I hope that my research has helped you all

cheers again!

Escort Cossie pumps areonly good for around 290-300hp.

The good thing with the bosch pump is that it sustains pressure even when under extreme loads.

The best way of you seeing this is to get a Fuel Pressure Guage and watch how it performs when you BOOT it! if fuel pressure drops as revs rise hard n fast, then worry.

If not, then you know that your engine is gonna be ok.

The other way of analysing it is gettin ya car on the RR and watch the AF ratio. if it leans out the by by piston. But you can do just as much damage by putting too much fuel in.

Which is why its always worth RR turbo cars, especially when u start uprating things

no worries mate.

its probably worth you buying the O-ring seal from nissan. Make sure it sits and seals properly or else you'll have fuel splashin outta the tank into the boot

Stuee,

as requested, my info on a selection of uprated pumps

go for either the one i and most others have fitted or the 220litrs per hour one. not sure on the size but its similar to the one Nana@OPtions uses

either way it will be better than the one u have and u WILL feel a difference.

hope this helps

see all the posts for alternative places these pumps have been purchased from

Jez got his for 80quid.

let me know how u get on.

Mate, I reckon it doesn't hiss anymore cos the 'o' ring on top of the tank isn't sealing properly.
It's worth getting a new one from Nissan and changing it, making sure it's in it's groove.
