Hello guys
I have a problem with heat I think.
Motor (348, newly rebuilt) is sitting in a 34 Tudor and runs fine for about 10 minutes and then if left running at idle it starts to hesitate and eventually stalls if I do not rew it up a bit. It hessitates and spits when trying to rew it up.
If I force the electric fan to run it goes away after a while.
Motor is equipped with 2 Edelbrook 500 on a Offy "medium" high rice.
The temp is about 180-190F (fan starts at 190).
And now to my question/suspicion, I have a fuel hose (black) from the gastank to the fuel pump and up to the carbs that is about 9,5mm diameter (0,38 inch).
This is running close between engine and the waterpump and seems to get hot. I suspect that the combination of large diameter and that it is tuching motor and waterpump to heat the fuel due to low fuel speed.
What is the inner diameter for the original metal fuel line?
And yes I have insulators between carbs anf intake (4gaskets and 3 aluminum gaskets, like a sandwich), can not get more in to close to hood!
Suggestions and ideas for solutions whanted.......!?
