Engine died

Mark, I think you need to wrap the line with insulation, or just ditch the mech pump altogether and get an electric so you can route the line away from there.

With the electric pump you can put the regulator on the inner fender and route the line across from there keeping it up out of that high heat area. Sorry for my off topic posts BTW.

As much as I wanted to run a mech pump because it's easy, the benefit of the electric pump and reg is huge, especially with a return line. The fuel stays cool and you never have vapor lock again.
