* Check fuel lines by pressurizing the fuel tanks to 10 psi and letting it sit for a couple hours.. look for dripping fuel.

* Check to ensure the pick-up tubes in the fuel tanks are not cracked at the top.

Overhead set was done a few months ago.

I do keep finding fuel residue around the pickup tube area and also around the saddle but the saddle is unrelated I believe and it’s probably rubbed a hole in the tank.Going to loosen that saddle when I get home and take a look. Does the residue around the pickup tube in the pic seem like that might be the issue?
