The amount of heat that get to the pump ain't going to do squat for heating the gas. Your over thinking the problem, "it's the gas", it has nothing with the motor.
You could probably machine a little off the pump face to do that but you still have all those lines running up against the block picking up heat. The new in-tank electric pumps are really quiet. Somebody probably makes a tank for these cars with the option for single or dual walbro in tank pumps by now?OK so this might be a little far fetched but what about a phenolic spacer for the fuel pump? Make a slightly longer pushrod and maybe a rubber gasket to try and seal off the pump from the block......but maybe more work than it's worth. Plus I guess that might throw off the geometry of the rod to pump arm. I just hate the whine of a electric fuel pump.
My other cars I install boat tank hand pump bulbs on the suction side of the mechanical pump. Works like a charm for cars that have been sitting up for a while or victims of heat soak.
Well, I took the advice above and went this route. Picked up a couple marine primer bulbs from my local West Marine this morning & they work like a charm. Just give it a few squeezes, then pump the gas 3 or 4 times and it starts right up.

Ask your marine parts supplier where to get ethanol free gas RC. Best to use it for all your small engines too.

now you need to fish one of these bad boys through the firewall, right next to the E brake release

That’s what we’re talking about; using the starter an extra 18secs to fill up the float bowl. If I start mine everyday, it’s like a new FI car; pump once, hit key, wham right now.I have Holley carburetors that seem to hold the fuel longer than any ThermoQuad that I have owned. The Demon 850 in my Charger holds fuel awhile too.
I have a 75 Power Wagon with a 440 and a Holley 600. That truck sits for weeks at a time unused but cranks and fires within 20 seconds even after a month of sitting.
Richard likes squeezing
Hopefully the heat won't do a number on the rubber bulb after a while?
Things that make you go UMMMMMMMMMMMMM.
