That filter between the tank and the pump is very coarse, just a metal filter to prevent large contamination from entering the pump - not a fine filter. Trust me, it won't restrict it.

Thanks for the advice; my experience with gas leaks is this (if I am wrong correct me). It is extremely apparent if you have a leak - your entire garage (regrdless of the qty of gas) smells like gas - really - really bad. I have had a small, small trickle before - and you KNEW you had a leak. Hard to see, easy to smell.

Since gas is extremely thin, and kind of spreads out (unlike water) gas seems to be able to seep into plastic and the SS hoses without being entirely visible and without dripping. But the smell is the dead give away...

Assuming all of the hoses are tight, the ends are tight, etc. How important is it for the top of the tank (where the sender is) to be sealed perfectly? I would assume an air link there is irrelevant becuase nothing is trapped in the fuel line process to the pump - correct?
