Greg - Couldn't find one the went from the 8-AN fuel line to 6-AN carb line. Not happy with the current system, thought about running old fashion steel or synthetic up from the pump. It will change at some point.........

Yeah, I would go steel and keep the lines low, down to a bracket at the front of the block then flex line to electric pump.....like what I did on this 69.... Looking good.

Thanks for the input Vince.

I never liked keeping fuel lines that close to the eng. Creates a lot of heat in the fuel...vapor lock. Don't you think?

Thats what I hear but I never had an issue. I like to have at least a 1/2" of air gap space around it. Nothing ever touching.

I think air gap manifolds and a phelonic spacer are the best defense against that.

I remember my Pontiac 400 and the separate lifter valley cover and "air gap" intake to keep the intake charge and quadrajet cool.

Thinking out loud.........The steel tubing could be wrapped in thermal barrier. That basic design has functioned well on commercial trucks for years w/o thermal protection. The line would be pretty easy to fab and it's cheap, simple and reliable. Synthetic tubing, nipple fittings and Oeticker clamps would be clean and simple too.

very true The reflective stuff works great on wire harnesses. But I remember most of the vapor lock issues back in the 80's were caused by a faulty fuel pump. Reduced fuel pressure plus slow fuel flow equals no cooling leads to vapor lock. Plus I'd take a 195 degree engine block over 800 degree headers any day.



back on track, Did you find a spacer? All I have are 1" ers.

Good points.

I've got three parts shops to check with tomorrow morning.

You may want to upgrade to PTFE / Teflon hose one day. It last a lot longer and is safer then braided/rubber I just re did all my fuel lines to it
