Fuel Pumps

Whats a good fuel pump for a turbo 12a application?
I think an external electric one like the stock pump is good.
Are there any almost stock replacement ( i mean like pull out old and the new one fits right in) performance pumps?
Im trying to keep things simple

sorry i've been absent from the forums for awhile im working hard on this. The 12A turbo motor is in the process of being worked on and I'll take pics when I get it back. Its getting tapped and all the new oil lines are being made. thanks guys!

I found this but its 4psi won't be nearly enough to feed this beast. Carter GP60504http://store.summitracing.com/partde...5&autoview=sku

holly pumps arnt to good for boost. you can get a walbro inline and i think a gsl-se pump will work.

you need your base psi. (7) for a holley i think, boost psi (10) and line loss (5) so you will need 22 psi. and a boost ref. psi. reg. like a aeromotive 13301 or a mallory 4307m or 4309.

check out turbomustangs.com for more good info.

Fuel Injection or Carburated?

A good one for a blow-thru setup is the Stock GSL-SE one with a Malpassi RRFPR.

Mallory Carb low pressure pre-pump, surge tank, Bosch/Aeromotive high output, Mallory boost sensitive return style regulator that can be cranked down to carby pressure.

As always...somehow contact Robert at RotaryShack....he's the boost pro.

Excellent so a stock SE pump could really handle it? Its going to be a side draft carby draw through system. Its basically the Arkay Turbo kit.

Ok so this is the fuel pressure regulator im looking at.
http://store.summitracing.com/partde...part=AEI-13301
I took rotospeed's suggestion. But then i was thinking im getting an rx7 fuel pump so why not a 93-95 fuel pressure regulator if it worked for them why wouldn't work with mine? Plus i think it'd be kinda cool to use as many stock rx7 parts as possible.

that looks good to me. its what i was going to get but i got a deal on a A100.

the 93-95 reg is for fuel injected and i dont think it will adjust down to the pressure that you need.

im also going to use a fuel pump for a gsl-se because i think it will work fine.
what carb are you useing?

that looks cool... i missed that your doing a drawthrough i dont think that you need a rrfpr because the boost isn't going through the carb.

I have never seen a draw through like that before. Usually it sits on a carb box huh. Cool!
