Silverad0 SS Posted May 26, 2012 Report Share Posted May 26, 2012 is the 03's a return style? Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted May 26, 2012 Report Share Posted May 26, 2012 (edited) Only the 03 are the return style, GM eliminated that in 04. With my experience in using fuel pumps with my blown vehicles, I always go with Walbro. My vette has a In tank walbro 255, my camaro has a 340 Walbro in tank pumo and a inline Walbro 255. I have yet to have a issue with any of them. The vette has heads,cam, exhaust and a procharger D-1SC. The camaro has a little more but with the smaller P-1SC. Just make sure to go a little above what you will need so if you plan to put more power to it, you will have the pump to handle it, instead of doing the job twice.

Stoshball Posted May 26, 2012 Author Report Share Posted May 26, 2012 Ok I've been told to get a Walbro 255 and that would do what I need but is that the universal inline model #GSL-392 ? And I am running a stock head and cam set up with no plans for major upgrades in the near future will the 255 install give me all I need running the P1 on the stock pulley and 42 pound injectors?

Stoshball Posted May 26, 2012 Author Report Share Posted May 26, 2012 Ok, i guess that's what I'm not really understanding. Do I need the inline pump, in tank pump, or the combination of both to run properly? Quote Link to comment Share on other sites More sharing options...
gmJake Posted May 26, 2012 Report Share Posted May 26, 2012 Intank cause an inline is not going to help pull more pressure out of a stock fuel pump. And i should have specified that you need the high pressure pump. That's not $100. Quote Link to comment Share on other sites More sharing options...
gmJake Posted May 26, 2012 Report Share Posted May 26, 2012 Inline is kinda like a backup for boosted engines. Quote Link to comment Share on other sites More sharing options...
Stoshball Posted May 26, 2012 Author Report Share Posted May 26, 2012 About how much does the high pressure pump run? Quote Link to comment Share on other sites More sharing options...
Thatdavidkid Posted May 26, 2012 Report Share Posted May 26, 2012 I run twin Walbro 255 pumps on my turbo car, and single 255's on all my cars in the past. Never one problem out of them. Just make sure you get the "high pressure" one for any boosted applications. Quote Link to comment Share on other sites More sharing options...
Cramer Posted May 29, 2012 Report Share Posted May 29, 2012 You have a few options on pumps. A boost-A-pump with a stock pump, single walbro 255, dual walbro 255's (one in tank and one inline or two in tank with a hobbs switch turning it (secondary pump) on and off), Aeromotive 340 or two in tank, Bosch 044. I also heard that Walbro finally came out with a 340 pump but i'm not 100% sure. With any higher pump upgrade it is good advice to upgrade the pump wiring also. You can purchase a hotwire kit, or make your own wiring harness. This will help the pump(s) run better to their full output, and put less heat to them and also minimized the potential for a wiring meltdown for the pump. Their are some good write-ups on them on this board, and they should help a ton as to what pump(s) to use and how to do it. Quote Link to comment Share on other sites More sharing options...
