Fuel Pump

[donwon]

For those of you that have changed out the fuel pump or know where it is; can someone give me an idea of how easy or hard is it replace it? Do you have to drop the tank? Are there any other parts that need to be removed to access it? Thanks in advance

Yes you have to remove the fuel tank to service the fuel pump. I have taken my tank out to fix an leak and its not that bad of a job. Just takes some time to disconnect the wiring and the plumbing. I did mine with the car on stands, but a lift would be better. The tank is light when empty so run it down if you can and then drain the rest.

Reinstalling the fuel hoses is a pain. The SM has ok instructions on removal/install. Be real careful working with open gas.

3 weeks ago working on turbo I removed the tank for the walbro 255 fuel pump install. The removal is not bad installing it back in is a pain.

Once you unscrew it from the bottom disconect all 4 hoses + electrical it comes out easy. Installing it is little pain because as you lift it half way you have to start connecting and it is easier to remove clamps then put them back on in tight areas.

Good idea to keep a fire extinguisher nearby when working on fuel systems too.

Don,
I had mine done at a shop nearby my house. If you want to call me I can hook you up with them. They did a good job. I had the Denso race fuel pump installed with stainless lines.

Hey all,

I'm looking to replace the fuel pump in my NSX with a Walbro 255HP pump; I've already got an AEM 1:1 FPR installed and configured for 40psi idle.

If you install a fuel pump with a higher flow rate than stock, should you still leave the relay that increases the voltage to the pump connected, or should you bypass it?

TIA!

Why not just buy a new oem fuel pump? Why go aftermarket??

Is the flow rate of a stock fuel pump to low?

If the A/F ratio is OK why should you go for a aftermarket pump?

The stock fuel pump won't be able to flow enough fuel for my application, safely, so I decided to go with a higher capacity pump.

Hi Brian,
Just out of curiousity, what is your application?

Best regards,
Gerard

I'm running a CTSC with the high-boost pulley, an AEM EMS, and a few other changes (550 injectors, a few other upgrades to the CT unit).

Hi Brian,

How about HP and what updates are you referring at? Sorry if this is going off topic.
Thanks,
Gerard

Target is around 340+ rwhp; I've also got a bored throttle body, polished intake manifold, and am considering a customer aftercooler for the kit.
