On my 1980 242 I have recently replaced the In-tank fuel pump.I have just recently bought this car, and do not know any history, except that it sat-up for "around 2 years". When I removed the cover plate to access the top of the tank, the larger hose was connected to the larger out-put fitting on top of the sending unit, and that's all that was connected. There are two other outlet fittings, one being the return fitting, that extends down to the bottom of the sending unit, and another fitting that just enters and stops under the top plate. There was a 1/4 tubing line laying nearby which came from the back side of the accumilator, next to the main pump, and I connected that to the return line fitting, leaving the ouher fitting line alone. Latter,I saw another tubing line laying off to the side with a larger piece of rubber hose ,hose-clamped to the end of it with a bolt incerted to the other side of the added tubing on the end. My question is , of the three outlet fittings on top of the sending unit , what hoses go where. I know I have the main out-put line correct, but the other I not sure of.Thanks in advance, Joe
