Fuel Pump Options R34 Gtt

[Bratva]

Hello,

I'm soon to get a tune and i need to decide whether to replace my current fuel pump.

Currently it is a Tomei one (276l/m i think) paired with 1000c injectors and stock fuel pressure. I have already done the direct voltage modification.

My hopefull power goal will be 310-330rwkw on e85. At the moment the current tomei pump makes an extremelly loud buzzing noise when hot or low fuel and after reading some things im sure it means the pump is on the way out (always ran on low fuel). Noise isnt grinding but like electrical buzz coming from fuel pump area like a transformer box sound. I havent noticed any fuel cuts or performance issues.

Question is would this pump be suitable for the power i want to make on e85, secondly is it recommended to replace the fuel pump when it makes a loud buzzing noise (intermittent) and thirdly what are my pump options (intank only).

I have read about the bosch 044 which flows less than the tomei so that is out of the question. Then there are some Walbros but i read the latest *e85* 460l/m one has some issues with priming when the fuel is below the pump level (read on this forum).

Please kindly assist and if someone can recommend a pump (budget of <300$) then please advise me where to get it from via here or PM.

Thanks

The Tomei should be good for 400 odd KW on e85.

The buzzing is normal when the fuel gets hot, put a fuel cooler in if you are worried.

Thanks, when i first put in the fuel pump it was quiet and after the direct voltage mod it was semi loud (could hear it from outside), but now its so loud i can hear it from the 20metres away, is that normal ?

How did you mount it?

Could've come loose and it sitting against metal, easy to check really and rule out

Tomei pumps are the same as nismo items aren't they? So they should come With there own cradle to mount in the stock position I think

[Bratva]

Yeah the Tomei one is the same as the Nismo one and everything fit as stock. I can have a look, not sure how else to test the pump. Ill try take a video.

When did you put the pump in? Don't forget with the hotter weather, the fuel will be getting hotter.

I use a BNR34 fuel pump in mine with no issues.
