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?

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.

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).

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.

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.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
