Minimum requirements for Aeromotive 340

[Captn]

I've tried searching, found nothing. I would like to know if it is OK to run this on a stock setup? Or what I would need.

You would need an afpr and a rewire kit to use a pump that large.

I figured as much as the afpr, nothing else you think? I mean I plan on using 560s and a 2g maf also. I just want to know when the best time to use it would be I guess.

Well its never a bad idea to go overkill on the fuel pump. The only problem is the overrun of the stock fpr. Id check the power requirements on the pump, but the rewire is probably required or atleast a good idea, to get full use of the pump.

But yea as long as you have a control on the fuel pressure it doesnt really effect anything else directly. Just fyi though, that pump is massive. A 190 or a 255 would also work great.

Heres a good link for fuel pump flow rates.

Also there's a very general equation for determining what fuel pump is needed. This may help.
HP x 0.42 = lph

Say your shooting for 300hp
300 x 0.42 = 126lph

A stock 1g pump with rewire would suffice.

At a minimum to use this pump, the rewire kit and AFPR, let alone, the ability to bypass the fuel not being used by the fuel injectors may require a -6AN return line from the fuel rail to the fuel pressure regulator. The stock fuel filter and feed lines are also going to be a large restriction if the stock banjo bolt fittings are still being utilized.

All in all, I agree that at a minimum you should do a fuel pump rewire kit with a 30A in-line fuse and either 8-gauge or 10-gauge power wire with quality high strand count wire (quality car audio power wire works well). Run a 10-gauge ground wire from the fuel pump ground to the chassis ground point.

As well, the fuel pressure regulator will be a must. Check out the Aeromotive A1000-6 adjustable fuel pressure regulator with -6AN fittings/line from the stock fuel filter with a straight M10x1.0mm to -6AN adaptor fitting with -6AN line to the fuel rail, then -6AN from the rail to the regulator and -6AN from the regulator to the stock return hardline on the firewall. Use a ProClamp (-6AN) (https://www.pegasusautoracing.com/productselection.asp?Product=3277)

Either way, it is a bit overkill for a stock setup. A Walbro 190LPH fuel pump will suffice, or a Walbro 255HP fuel pump will work for less money.

Thanks for the help everyone, very friendly and quick!
