Hello people, I've had a hard time traveling in my YJ. Everything was ok until I stoped by a grocery store. The engine have been having some abnormal behavior, I've been smelling fuel when I shut off the engine and step out of the jeep, when the tank is not full (say 1/4 of the tank) and I open the gas tank cap it releives a lot of pressure. If I let the jeep sitting overnight, next day will give a hard starting and I have noticed that the carb bowl seems to be empty, as I can see there are no squirts when the pedal is pumping. Now, regarding the day it completely failed, it was starting and then stallin unless I give it a hard acceleration, then start moving and it would keep the engine running for a while then dies. Started troubleshooting by checking the squirts in the carb. No squirt. Disconnected fuel hose at fuel pump inlet. Completely dry. Attached an electrical reciprocating fuel pump. Same behavior after a while. Fuel filter replaced with a single outlet one to eliminate return line. Could get the engine running longer but sometimes carb was flooded and sometimes I heared the electrical pump noise which means it is empty. I've decided to get back home with the single oulet filter setup and both fuel pumps connected in line. The engine runs great even in hard acceleration when overtaking other vehicles. But if I slow down in traffic I will hear the electrical pump is getting dry again. Now at home, tryed a new fuel hose from an external gas tank to the electrical pump. Same thing. Routed a new fuel hose to bypass mechanical pump and steel line over the engine. Same behavior. I've tried removing gas cap with no difference. I've rebuilt the carburator and noted the base gasket was just with two barrel holes and no grove on the sides to let vac flow from the port that goes to canister (I think). Replaced that with the oval hole and side groves. But I'm still getting the pump dry. As this is my DD vehicle I'm in a rush to fix this problem asap. Any help will be highly appreciated. Going to drop the gas tank right now to discard pickup tube clogging.
