Is there somewhere that I can get a diagram of how the fuel-line should be routed from the fuel pump to the carburetor under the hood of my 89' YJ with a straight six? It appears that originally there was a metal filter with one inlet and two outlets that mounted in the fuel line just before the carburetor. I now have a plastic see-through filter with only one inlet and one outlet. I'm guessing that there are some vacuum hoses that are improperly directed or plugged also. The engine seems to starve for fuel under load and I'm trying to determine if fuel supply is the problem.
