Replacement Fuel Pump For R34 Gt-T

[*JaR*]

Recently bought a full exhaust ( blitz nur-spec r ) pod filter and blitz fmic for my 34, ive been told i should also think about changing the fuel pump with installing these mods? If thats the case whats the best option?

Why install a new fuel pump? A new pump will raise pressure and if your narrowband is old and gritty it may not do a great job at leaning out the new mix. Get your self a bleed valve and a tuneable ecu.

Thanks i did have a search around and found the answers i needed. Been a long time since ive used the forums.

No, it shouldn't raise pressure.

Also i didnt want to start a massive debate over that comment but i did an aftermarket fuel pump replacement when i had my 33, had the bosch 040 put in and it didnt raise pressure all i wanted to know was what a good option for the 34 was.

[wolverine]

Walbro will get the job done.

Which one?

[Joshbigt62r]

Nismo drop in. Or a e85 400lph walbro will do the job Thetis drop in models for skylines on eBay for around $200ish. There is a 450-460lph version swell that's drop in. You may as well go a e84 friendly one for the future.

pretty sure the e85 pump is not drop in. I have one, it is in but took some mods as it is a fair but bigger than the actual drop in pump, and it draws heaps more current.

[Joshbigt62r]

I know the nismo pump is 100% drop in. The e85 460lph walbro make not be direct drop in but it is a intank fuel pump still. And still can be a drop in with a bit of basic mucking around. So yes it is a drop in fuel pump still as if drops into the tank. Just not a DIRECT drop in as the nismo pump is. keep in mind though the walbro is basically hAlf the price of the nismo.

Thoughts on the bosch 040 as opposed to both?

[scotty nm35]

Don't use the 040, the filter is prone to clogging and it is an old clunky design.

The Walbro 460L is overkill if you aren't tuning the car, even a Walbro 342 is more than you need, only costs $100, but still requires hard wiring the power.

I would be keeping the stock pump until you decide to tune it.

Ok sweet thanks for the help :-)

[Joshbigt62r]

As has been covered Bosch 040 is poo compared the walbro pumps. Really depends what your future goals for the car are. That will determine which pump you use mate.

Chunky yes... I dont know why people use the 040 over the 044 as i ran an 044 with barb on the end and the original style fuel sock on the bottom of the tank, should solve that clogging issue... Worked perfectly and surprisingly wasn't loud! I blamed it for my fuel issues but it ended up being the injectors! I still run that same pump today but its now in the boot due to the external setup.

[Joshbigt62r]

What does a 040 flow and what's a 044 flow? Sweet f all compared to the new walbro's

A single 044 got me too 350kw on an intank setup! How much power do you want to make? lol

[Joshbigt62r]

I've got a single 044 that has been made to be a drop in. From memory I had to modify my cradle to make it a drop in. I put that in probably 5 or so years back. If I were to do it today I'd just use a walbro e85 friendly pump. Well plans are for me to make 400kw if I can. So I'll need to upgrade my pump. If memory serves me right the 044 flows 300lph but I could be wrong. 5+ yrs back memory not so great from regular weekend alcohol abuse haha. I'm more than likely still going a hta 3076r or 3582r on my built 25. Unless stao can come up with something pretty similar. Prefer to support a local bloke if I can. But FP hta just seems the ducks nuts at the moment lol.
