Name This Fuel Pump!

[joeyta22]

Hey guys,

Just trying to confirm if the fuel pump in my car is indeed a tomei one as advertised. There is no part number or anything on the casing and seems to slot into the stock cradle just fine. I've tried googling and all the pictures are tiny and hard to distinguish, but from what ive read the stock pumps have the part numbers on the main body of the unit however this one only has the numbers shown in the pic below which isnt on the main casing. So does anyone recognise it and/or confirm it's a tomei item?

Looks like a stick pump? What year \ model is your car?

[Guilt-Toy]

stock gtr pump maybe

[JustinP]

It's definitely not a Tomei pump....

I have a Tomei pump here, direct replacement for r32 GTR, it looks exactly like the one you are showing.

the stock pump has "made in japan" and "JECS" stamped on the body. Not sure why some Tomei one look different, but the one i have was purchased from japan while over there and is identical to what you have.

Also my car was running out of fuel, 100% injector duty cycle 700cc, replaced stock pump with the tomei and it richened up the top end, so seems all sweet.

nismo or some other "slightly larger than stock" pump.

Name the fuel pump...ok... I name it Barry. Sorry I cant be of more help but its worth a laugh

[joeyta22]

Thanks for the replys guys. At a glance yes it looks stock, but the fact there is no stamps or anything leads me to beleive otherwise. Some more searching led me to think it may be a tomei pump for a gt-t as per... http://www.nengun.com/tomei/fuel-pump-nissan-skyline-r32-gts-t it looks awefully similar.

Car is an 89 r32 gtr. Good to hear about that blue_vl_t, its pretty much the problem i'm having atm where the towards the end of the revs its starting to lean out, also using 750cc injectors with stock fuel pressure reg... might change the fuel filter for a new one, otherwise ill be farkeds why its leaning out (rb26, -7's, supporting mods ect, looking around the 320kw mark).

[blue_vl_t]

yep, well the stock fuel pump will run out of legs about 300 rwkw,

if what you say is true, i wonder if the gtst pump is rated to the same flow? it fit straight into the gtr, direct replacement, so yea?

[joeyta22]

Going by the nengun site for R32 tomei fuel pumps...

GTS-T = Out Put 540PS 248 L/h Standard 136 L\h

GTR = 590PS 276 L/h Standard 195 L\h

So gtst pump is rated to a little less but should still be plenty.

if it's running out of flow at 320kw it's a stock pump. genuine tomei/nismo/sard pump will easily flow 400kw. it's easy enough to test on a dyno with just a fuel pressure gauge.

my nismo pump looks like that!!

[joeyta22]

my nismo pump looks like that!!

Did you purchase it brand new from a reputable place?

[Moodles2]

Tomei and Nismo pumps are the same, I can't remember if Tomei supplies them to Nismo, or the reverse

[blue_vl_t]

anyone know if a gtst pump fits straight into a gtr, (R32) ?

as this pump fit straight into my r32 gtr

just trying to clarify if its a gtst nismo/tomei pump

anyone know how to tell difference between gtst and gtr pump..

just pulled mine out pretty sure its stock pump. has jecs on it...

i was told it was changed but probably BS...

[ARTZ]

anyone know??

[blue_vl_t]

bit of an update on this situation, so the first pump pictured at the top of this thread is what i'm running, 32gtr, wound the wick up today 1.5 bar and i can easily run the afr into the 9.0 reigion if i nneded to. i supplied the pump with a direct feed from the battery and a relay.

so it seems to be flowing quite a lot.

Mods.
