Colin,
I don't remember where I got the T'stat from, but I think it is a late
model 160F from someplace like AutoZone.

Done that when I first put her back on the road in 93.

I had the rad recored back in 92 when I was restoring her. So that's
new.

The fuel line on my 4/4 isn't too bad. It comes up the the driver side
on the inside of the body, and the exhaust is on the outside of the chassis.
Then it comes across the firewall to the pump on the pass. side (left hand
steering). Then a metal tube goes along side the block and up to the carb.
The exhaust manifold and pipe is on the drivers side. So unless the eng.
compartment is very hot, or the heat coming off the exhaust manifold is too
much, I don't think I really have a problem with the fuel line.
But I was thinking about trying to find some sort of foam insulation like you
can get for you house water pipes and see if that helps any.
The thought of the electric fuel pump is being concidered. If for nothing
else that to fill the float bowl when it's empty.

Now that's a thought. I seem to remember hearing something about jet coating
keeping the heat in the manifold and letting it go out the exhaust pipes. But
I don't understand it.

Thanks for the input. One of these days, I'm going to have to try all these
things and see what does what.
