I welded up some of the extra hoses in mine, I left one lower and one upper, I "T"'d thise lines together and ran a single line into the filler nick and removed the expansion tank, when I sumped and sealed my tank, I do get some starvation if I have less than a half tank on a long sweeper, I drilled many holes int he tank above the sump, I should have only drilled one in the middle to reduce the abulity of the fuel to slosh out of the sump
