calebcj7 OK guys so sorry about taking so long to get back to you, ive been extremely busy with high school starting back up for me. I found the problem!!!! Turns out that there are two vacuum ports on the carburetor which were capped off, but both of the old rubber caps were cracked and not sealing, so i replaced both of those, and she goes up the hill with ease now!

Thankyou so much for all of your guys' help, and Speig, I am going to convert it back to the oem fuel filter set up like you recommended.

layzdude I had the same issue on my 86. When I dropped the fuel tank to replace the sending unit I Pinched the fuel line. I would check ha first. Disconnect the fuel line right before the fuel pump and use a gas can to see if it run directly from there. You an also pinch the vapor return line and it should give it enough fuel to run. I always keep a clamp in the console. Hope that helps.

LumpyGrits Go back to OEM filter set up and see what happens.
Pull the top of the carb off and check float setting.

I assume you are on the the gas pedal more while climbing a hill than you are on flat ground?

Spieg8 Does sound a little high. That's the other purpose of the 3-port filter excess pressure is released bock to the tank via the return line.

calebcj7 Just measured 9 psi of pressure coming out of the fuel pump, is that too much? Looked like it should be around 4-7psi based on what i saw online.

The return port will be off center and the filter should be rotated so the return port is at the top or 12:00 position so any air in the filter will go back to tank rather than to the carb (vapor lock prevention).
OK ill check for leaks,

I don't have a normal fuel filter in the lines, i have a boat filter for seperating water out of the line, (my jeep used to be a plow rig, guessing because condensation may have been getting in the tank) This filter is between the tank and the fuel pump, and then i have hardline going from the fuel pump to the carb.

But if it had fuel starvation wouldn't it stall even on flat ground? mine seems to die only when going up a big hill by my house.

Not sure on the needle valve, again it's been a while, but if there's a hole in the float you basically don't have a float any more. You have a piece of metal with gas in it. Should be pretty obvious when you crack it open - there'll be gas in the little grape-sized float(s).

If you can run a hose from the fuel pump at the tank side to a small 2 goal fuel can and strap it to the hood or something you can find out if it could be the pick up in the tank, etc. Is the problem or if the problem is under the hood.

If you can't keep your hand on it-That could well be the issue.

WindKnot New means new. It doesn't mean better or that it works. Check the float.
