bought this to fix fuel drain back problem

I am afraid this did not help as hoped. My symptoms remain. I put it in about 8 inches from the carb, for what it's worth. Worth a shot though; next, think I'll try an electric pump inline.....
.....though I did think I'd stick a primer bulb n hose under my seat to pull out n squeeze, just to see the expressions on my passenger's faces!

No telling what they'd think was going on under that seat if I wore a leering grin as I pumped!
