yay or nay? and what other parts can we use from the good ol' FD?

i am pretty sure pretty much any fuel pump works on pretty much any car as long it will flow enough. i am pretty sure it will work fine though.

The fuel pump works fine. You don't need the filter.

GEINN FC3S

what if my fuel filter is bad and i wanna replace it? will the FD one fit?

NZConvertible

The FD filter is mounted in a different location, and has connections that point in the wrong direction, so it'll be a huge pain to fit. IIRC they use the same size fuel line, so they'll flow just the same and is not an upgrade. Just get a stock replacement, they work fine.

alrighty then! thankx for ALL the help!

It's a drop in fit for a Kouki FC. It takes a little bit of modifying for a Zenki FC.

Why you want an FD fuel pump for? It's a piece of junk.

FD pump > TII pump, at any rate.

but if you're going to do that you're going to wish you got something else later on anyway.

which is why i sold my fd pump.

I do not understand that chart. At 0 psi, it flows 72gph? and at 100 psi, it flows nothing? or are those two points not useable?

'splain, ted.

GEINN FC3S

youre right! im prolly gonna go with power enterprise one!

"0psi" is the free-flowing flow rate with no pressure - basically, you measure the flowrate right after the fuel pump outlet with nothing connected.

The 100psi is called the terminal pressure, and you plug a pressure gauge at the end of the fuel pump output and read the gauge. Nothing is flowing, and you're just measuring the max pressure a fuel pump can output.

You've said before that it'll support 300hp on an FC. Why is it now a piece of junk?

RETed

Yes, let me qualify that for you.
The Walbro 255lph high pressure fuel pump is an excellent upgrade for the money. You got a BRAND NEW fuel pump that easily supports OVER what an FD3S stock fuel pump can do. Why spend money on a USED fuel pump that doesn't support as much? The Walbro unit will also run the engine richer due to the high flow capacity, and this might save your motor. I had my wastegate line *fall off* my turbo compressor housing when a bunch of my friends were driving it. The telltale on the 60mm GReddy boost gauge showed 17-18psi of boost peak. I credit the Walbro for keeping the overly rich mixture, or I think the engine would've been toast. No, there was no hint of detonation - I do have a J&S Safeguard installed also.

If you get the FD3S fuel pump free - sure, go for it. Else, I wouldn't spend money when I can get a Walbro.

What did you think I meant?

Yeah, I know a new Walbro will be better than an FD pump, but I'd hardly call a 300hp fuel pump "junk".

You could just as easily argue that a Walbro is a waste of money for a sub-300hp engine if you have no plans on exceeding the FD pump's capacity. In that case it makes better economic sense, even if you include the cost of a pair of new hose clamps for the wastegate line, just in case...
