Steve, what I did was run a 3/8" diameter line from the back crossover
pipe, stock is 5/16", and run it up along the firewall, close to the
booster. It then has a short rubber flex line, connected to a steel
line going to the carb.
I have a Holley dual inlet, and use the common 2 into 1 line.
The setup keeps the fuel away from all that heat that the line picks up
on going by the exhaust manifold/headers, front of engine block, over
the top of block, where it picks up heat.
Now of course, you could run insulation along the line near the engine.
Also run a heat insulator between the carb and manifold if you have
hood room. This transfer of heat is what cooks the gas, but elec. pumps
help a lot, as opposed to the old mechanical pump.
Now there was this time when I was driving the Dynamite Truck during a
summer job, and the old flat head Ford got vapor lock in front of the
Supreme Count and stopped.
Cops were all over me and that Red Truck, with Dynamite lettered on the
side, wanting to know what I was doing driving in this restricted area,
this was back in the late 50's.
Well by the time the shop mechanic got there, 1/2 hour later, it cooled
down, and started right up. It had a push button starter.
I don't know who was more relieved, Me for not getting a ticket or put
in jail, or the Cops, who didn't really know what to do with me and the
Dynamite Truck in that 1/2 hour.
True Story.
But I think the gas line looks so much neater tucked away in this
location next to the firewall, and no heat.
