New fuel pump ??

[Andy Kain]

Bit of advice needed please.

When I drive my R34 GTT at around 100 -120 mph (noticed this whilst running at SantaPod a few weeks back), the car seemed to lose power for a fraction and then pick up again, could it be time to upgrade the standard fuel pump? and if so can anyone recommend a good manufactuer and has anyone done this themselves or would it be better to get it done professionally?

Cheers

Andy

Ditto, i hear the best thing about this pump is that it's a direct replacement?

I wouldn't use a Walbro if I got paid to do so, I have seen them fail and fuel is too critical of a component to take a risk on.

If you can afford then I would choose a direct replacement from Nismo, HKS etc.

I seem to have something lodged in the memory about an issue with the GTT at the speeds you mention but I can't remember the rest lol

Maybe that will jog someone else's memory

Is that a direct replacement?

Not sure if that one is a direct fit, I found this page on Nengun skyline fuel pumps nismo

I had a Walbro on my GTT and although it was rated at whatever litres per hour, it couldn't sustain it and the rate dropped, so in went a Nismo R34GTR pump. The GTR pump certainly wasn't a direct fit, infact I thought "how the feck am I going to fit that" But it went in with a bit of adaptation and I can only hear it when I'm backing the car into the garage, unlike some pumps I have heard.

On the grapevine, I've heard that the Tomei 280 litres/hr intank fuel pump is at the top of the tree & the same goes for their ultra-reliable oil pump upgrade too, though devilishly expensive!

Ask them if they have it in stock or your wait for ages

Yeah I forgot, last time I got something from Nengun it took 7 months to get here

i mostly fit the HKS 280 l/Hour pump (its listed for the gtr)

you have the choise of ****ing about with the tank bracket or buying the GTR bracket (which i keep in stock )

You got it in one!!!

If you want a Tomei pump get it from Rod Bell (RB Motorsport).

Nismo 280lph in mine, direct fit.

are the R33 GTS-T pumps the same as the R34 GTT pumps?
I am having fueling problems either faulty walbro 255 pump or not the correct voltage getting to it.

The fuel pump is only 6 months old so should be working okay. It is a 200sx pump but has the same fitments as the R33.
Should I change to pump?
What should the voltages be at the fuel pump on idle and drive?

Does any one run these?
