Nismo Fuel Pump Q R33

[boostn0199]

just got my nismo fuel pump today and wondering what this part is that came with it?

Think its a check valve, goes in your tank between the fuel pump and the cap

It replaces a purple stock fuel check valve (i think its purple? or brown?)

I didnt put mine in and it still works fine, but if I'd known thats where it went would have done it when i did the pump

Someone clarify its a check valve? i think thats wat it is?

Yeh its the check valve. Mine isnt in either.

Congrats on the purchase! The Nismo intanks are the best on the market!

As above, I put mine in and then had some issues that turned out to be a fuel reg, but I'd taken it out while I was searching for the fault and never put it back in.

The Tomei Fuel Pumps are just as good

Lol seems none of us have the check valve installed

[tridentt150v]

Well i wondered how it worked anyway............I could see straight through mine, and could blow through it as well.......didn't seem to be doing much check valving.

Also when I installed it, the pump still primed up anyway, so I reckoned it was pretty useless, cos it's supposed to keep the prime up. I didn't notice any diff whatsoever when I removed it.

its a relief valve . not a check valve .
