External Fuel Pump Recomendations
Thanks
Pump... the Impala SS feed a Iron version of the LT1. They will feed a stock or mild LS1 ok. Walbro 255 in tank will handle most out to 425+hp ??? Check out Racetronix.com for a B-Body pump and wire kit.. or any of the B-Body internet stores for the correct pump. I installed the Racetronix B-Body / Impala kit on my Chevelle project.

How is the fuel pressure regulated on a stock LS1?
If I keep the standard LS1 '02 fuel rail can I run a adjustable regulator for the return line? What size lines will I need to run? Will a 255lph pump handle heads/cam LS1 + 150 wet shot?
Thanks
I am running 3/8" input/output for the feed and 5/16" return.. u can alway go bigger. I used some Russell Quick Dis-connects (#640850 & #640860, aobut $15 each) for the lines to AN -6 lines. You can alway braze on some AN connector.
I think the 255lph will handle another 150, but suggest you get input from someone who is doing it. I am only running mid mod for a street driver.
Good luck.
If you going to use the OEM accessories (A/C, Power Steering Pump, Alternator) as I am, then BRP mount are the way to go. If your going to use After Market Accessories, the S&P mounts. S&P makes very good stuff, but costly.

I originally used the Stock F-Body pan, and it would have been ok, but leave it to me to do better.. I didn't like the 3/8" or less of clearance for the pan to x-member and teh right rear head and A/C box. I picked up a Cadillac CTS-V oil Pan from a take-off and used that to give me much more room around the frame, only con was that the pan is lower by about 1", but wayless than a truck pan. I am not slamming my car to ground, so it should be an issue, as there are other things that hang just as or lower that the pan at this time.
I am using Energy Suspension SBC Tall and Narrow engine mounts and narrowed the Frame mount by 1/2" inch, which is more than the tall and narrow mounts. I use spacer to jack the engine back and forth to center the engine and the two area of contact that I encountered. That being the Power Steering pump and the Steering Box on the front and the right head and the A/C box.
I have some other thread input on what I have done, search for CTS-V for the pan and a few other thread, one is this.

Oh yeah. No news on the fuel sender but I will let you know. If I had the tank already I could just hit it with the multimeter. I'll let you know when I find something out.
I made that master bracket. You can buy them for about $75.00 ... but me being the cheap guy, costed my some scrape and time. I use some 1/8" plate metal and cut and drilled to get it right. I pulled the size, holes and shape from the Digram from the S&P web site of there 70' LS1 install. Was not hard to make.
Yeah, buget.. been 3 years of saving and cost cutting and It's sill hard to beleive that I have spend that much on it. Body, interior, suspension, drive train. But you gotta love that $$$ pit LOL.
I used a lot of info from both S&P http://www.hotrodlane.cc/70chevelle/1970ls1chevelle.htm
Talked to Phil at BRPHotRods.com
and JohnB's site, his Monte is very close to doing a Chevelle.
