Stalling when cruising up hills...
Took the car out for a spin yesterday and today. Had NO problems whatsoever. Sang through the RPMs without trouble, idled fine, and made me actually relax for once..
But today when I returned from seeing some family who live out there where there are quite a few hills, it started having problems. When I'm simply cruising up a long and not necessarily steep hill, the car starts to buck and stall and want to die. I remedy this, I have to get it out of gear, and feather the throttle until it revs smoothly, then put it back into gear...but if I'm still travelling up the hill, it will continue to do it until I get to the top.
It has no problems going up short hills, or accelerating fast up short hills...but give it a gradual incline over the distance of a quarter mile, and it wants to cough, sputter, and die.
I've played with the carb, but nothing seems to work..

Fuel pressure is a constant 7-8 psi.
No fuel filter that I am aware of.
Brand new Summit HEI distributor..no external coil.

Full tank. But could it still be the fuel pickup line? You'd think that if it were the carb, I could replicate the problem without having to find a back country road, with hills... It's a gravity thing. So either the fuel pickup line, or the fuel level in the bowls of the carb..

How do I pull the sending unit? Do I have to drop the gas tank to do it?
