tomei fuel pumps - need advice.

[performance-wise]

I just purchased a Tomei fuel pump for my R33 GTST.

heres what I got:

- Pump and bracket with sock, wiring etc..

- Rubber O-ring for lid??

- 2x hose clamps

- what looks like a pressure reg?? (has "A VALVE CUT" written on the box with part number "17065 - 05UOO"

Im clear on the pump and bracket and I am assuming the O-ring is for the 'jar' lid for the fuel tank.

Not sure on the pressure reg thingy though??

I havent had much to do with fuel regs and I am reluctant to install the pump untill I find out exactly what this part is.

Anyone got one of these tomei kits before or can anyone advise me on what the "A VALVE CUT" is?

Thanks in advance.

i have a tomei r32 gtr pump in my s14 and it came with that little pressre relief valve as well.

i believe its for a stock car to buffer the pressure and to keep it consistent with stock bits, but i have an adjustable fuel pressure regulator sooooooo i opeted to leave it out, hasnt caused any problems yet.

So they are an upgraded relief valve to coincide with the upgraded pump?

Ive also got a NISMO adjustable fuel reg (yet to go on) but I wont be doing this till I get my power fc tuned next (proabably when I upgrade the injectors).

Should I replace the stock relief valve with the one supplied when I install the Tomei pump? Or will this require a retune of the power fc aswell?

thnx.
