OK, here it is. I have an '87 MCSS. Getting a 425 hp 383. Eventually turbo/SC. Looking for 450-500 at the wheels. I purchased a jegs 130 gph electric pump. The original plan was to make a bracket and bolt it to the spare tire well behind the axle. Jegs tech said it won't work if I use the stock sender. So, if they are right I need a sump or a cell. Problem is I ran out of $ for the swap. What's the most cost effective way to make this reliable?? Will it work mounted to the spare tire well? I will be running new 3/8 line and maybe use the 5/16 vent for a return.. Really don't know which way to go. If I need a cell is there a bolt in that uses the gm sending unit? Any help or experience is greatly appreciated. Oh and the block isn't folly drilled for a mechanical pump. Last 1/4" is still there. Vortec 4 bolt block. Eventually looking at maybe 8# of boost. Would like to do this once if financially possible. I have to get this done as it is my DD and the 305 is half dead. Thanks.
