What is the easiest way to add two return ports to a glassed in gastank? I understand this is the way to fix a vaporlock problem on the 502 efi engines.

i think the easest way would be to buy a fitting that cpperformance sells that goes into the rubber hose that is your gas fill.it has a tee fitting and you can return the fuel that way.i have heard sooo many ways to fix the vst injection that i cannot rember them all.i have a 94 fountain w/the same problem,rough idle,vapor locks sometime,etc,etc.let me know if it works,i am about ready to can the injection in favor or a carb.just dont like the consumpton of a carb vers injection.good luck.
