Re: what diameter is LS1 fuel pump?
Yeah I had read there were pressure differences with earlier EFI and that the pumps vary some by application, but I was wondering if the diameters and lock mechanism were the same (figuring the length of pump assembly might have to be altered).
I'm putting an LS1/T56 in a 67 Camaro. I have read about people sumping their original tanks and using an external pump, but I don't see a robust way to mount the pump lower than the tank as the tank already sits so low in car. I've read about guys welding the new in-tank pump interface to the top of their tank and all of the sumping and starvation issues they have. Then of course there are the large number of folks that buy the aftermarket EFI tanks, and it seems they all have issues (and costs ranging $600-$1200 or more). I would really like to avoid $1200 for a fuel tank.
So I was thinking an older OEM tank probably has the sumping and baffling that would work. Came across this mid-80s Olds tank that is about the same size as the 1st gen tank and even has the inlet in the rear, so was considering it. That's what prompted the question...
Thanks for the quick response and interest!!
