tricks in troubleshooting fuel syst. leaks

[cemiiii]

i have dual tanks with a switch and a water seperator and 2 motors attached. i have been working for several days trying to find out where the system is losing its seal (I cannot get the bulb to firm up like it should). i've tried double clamps, isolating parts with vice grips, no luck.

what are some of the tricks of the trade you pros use to troubleshoot the fuel line system?

thanks, chris

if it is an aftermarket bulb. point the arrow to the sky. they have a very cheap check valve in them.

Did you check the o rings in the quick disconnectors if that is what you have?

new omc bulb, every line and connector replaced with new, still leaks somewhere. omc (johnson) terminal connectors and same thing on both tanks. chris
