A friends son has an Issuzu Trooper with problems;
There are apparently three lines that come off the top of this fuel pump which are connected to various locations.There is a fourth rubber hose that is connected to the bottom of the fuel pump which is not hooked up to anything and is dripping gas. This is a carburetor engine and the question is : is that bottom hose and external vent or should it be hooked up to something and if so to what?The fuel pump is a mechanical lift type off the side of the block.
see the attachment...where does this hose go?
