I have a 2000 38 Lightning and I am putting new to me engines in it. The fuel regulator has an overflow outlet that needs to go back to the tank. Does this tank have another bung to accept a return line? I have not looked but plan to tonight.

No, I did it for someone recently, purchased every thing from Hardin and it goes in the fuel fill. it was very easy

My 2001 35 had bungs next to the pick-ups I just plumed in there!

I did the same thing cut the fill hose added the fitting and piped in the return form my regulator

Do you have a 6 port fuel valve to return the fuel to the tank your sucking from ?

Not sure. I am under the impression that the pressure valve has an outlet that you plumb back into the tank.

You have to return fuel back to the same tank you are drawing from !! hence the 6 port fuel valve , supply & return per tank .

gotcha

Why not return it to an unused in port on the water/fuel separator?

best to dump the fuel back to the tank .....the return fuel with have elevated temperature and needs to be cooled back down in the fuel tank .....m
