Which fuel pump?

I'm going efi turbo fellas and need help on which fuel pump to use out of the three I have here?

1. http://www.summitracing.com/parts/AEI-11109/

2. GSL-SE fuel pump

3. Walbro 255 lph

Needs to be capable of fueling 350 whp. I'll just move up to a aeromoitve a1000 pump once I need more power. Going to change fuel line size to stock GSL-SE size.

Walbro

I would go with the high pressure Walbro HP 255 lph.
That should be good for at least 500 hp.

high pressure

I believe GSS342 HIGH PRESSURE would be the one to get since it will allow you to up the pressure and flow to possibly avoid the cost of larger injectors as you make further mods.

I was looking into those. They seem to all be intank pumps though. I'm looking for external.

On summitracing it says the GSL392 is a high pressure external pump so i'll probably go for that.

the bosch 044 actually flow's a lil more than the walbro, and it has the added bonus of being e85 compatible, that's what im going to run on my setup even tho im blow thru and it's somewhat different but just my 2 cents

+1 for the Bosch -044. It's made for a turbo car (Porsche 911 Turbo), so it can maintain the pressure you'll need at higher boost levels (if you ever decide to go there). I'm running one on my turbo 13B-RE, and it has provided rock solid fuel pressure up to 14 PSI of boost. It can be mounted either internally or externally.

Ya, I'm upgrading the fuel lines and also looking into a GSL-SE fuel tank. The thing I like about the Walbro is it's the cheaper route. It looks like on the outlet for the Bosch I will have to run AN line which is good, but more exspensive. Or I can use this http://www.summitracing.com/parts/RU...3/?image=large.

Will 5/16 fuel line be big enough for main and return or should I go with 3/8?
