boiling fuel

Thanks All,
Sounds like some re-plumbing is in order. Makes sense though. I was surprised at how hot the carb got also. Gail Shaw runs an insulator block to isolate his carb from the heat on his driver. Makes me wonder how these poor things ran back in the day when they were totally stock! Having that fuel pump directly over the exhaust scares me also.
I have a bunch of that loom. We use it on the bikes wiring. Oh yeah, we use in the electrical trade also. I'm an electrician, or at least I was 2 years ago before the industry halted. 32 years in the trade, non-stop, then a sudden road block with only a few more years to go. Frustrating.
Thanks for all the tips, RF.

Part of the problem is that you are routing the gasoline thru the old fuel pump. It sits at the hottest point of the engine and is now nothing more than a heat exchanger, taking heat from the manifold and transferring it to the fuel! Let the pump sit there for looks if you wish. But run the actual tubing around it.

red, As you are in SF, Sacramento vintage Ford in Rancho Cordoba sells the loom.

I think the material Tim is talking about is wireing loom available at most vintage wiring suppliers.
CORDially Mike

Red Fred: My fuel line comes up the middle of the firewall, then over the top right side of the engine to the carb.
Can't remember where i purchased the insulation; seems as tho any good shop or resto store would carry it.
CORDially, Tim.

Thanks for this Tim. Would you remember the brand name by chance, or where you found it? Since you by-passed your mechanical fuel pump, did you plumb solely on the left side of the engine?
I'm interested on how top mounted fuel pump cars have their lines routed originally.
It's always something!
Thanks, RF.

Red Fred: I'm running an electric fuel pump also- exclusively. By-passing the mechanical pump. My electric pump is on the left side of the frame just forward of the fuel tank. I have double insulated the entire fuel line from tank to carburator using the black cloth-like insulation. The thinner insulation that fits snugly to the tubing, and then the fatter over the top of all that. No boiling.

Another maladie I'm experiencing is bubbling fuel in the top mounted fuel pump bowl. I've gutted this mechanical fuel pump, and only use it as a site glass, as the fuel is pumped through it via an electric pump & regulator.
The regulator is mounted next to the gen on the pass. side, and a steel fuel line runs along side the pass side of the carb, with a loop bent in the line on it's way to the old, stock, gutted pump.
Operating temps seem fine, and low (I have external pipes, but am not super charged), but the fuel is bubbling fiercely in the site glass. Luckily, I have been able to restart the car when it's hot, but it is a chore, compared to when it's cold.
Any ideas out there on keeping the fuel cool?
Thanks, RF.
