Fuel system alternative
I simply adapted the LS1 bucket system to work. What I did was shorten the stock LS1 bucket as much as possible, down to the height of the pump. I tossed the whole top half of the system in the trash, minus the springs. Then I cut a hole in the top of my stock 73 tank, and dropped the bucket in. I then got a third gen sending unit, tweaked it to fit into the 73 tank, tweaked the float/sending unit to read correctly, and ran a fuel injection hose from the fuel pump to the 3rd gen supply line. The height of the pump and rubber line poses a problem with kinking as it exits the pump as it is right ont the top of the tank. I set the pump in the bucket slightly crooked and then inserted a spring into the fuel injection hose to prevent kinking. Conveniantly, one of the springs you saved from the 4th gen fuel pump assembly fits perfectly in a 3/8 hose. I then ran a return line from the 3rd gen unit back into the bucket assembly. Went ahead and made a cover for the top of the tank and sealed it down. Solves every issue I was concerned with. Works just like a factory setup, only it was $40 bucks for hose and clamps and the 3rd gen sending unit.
Post some pictures of you setup. Other many find it usefull.
