Mechanical fuel pump problems

Ditto above...not 100% sure, but it seems to me there are two bolt on mechanical pumps that fit, but have different a lengths. I've always used the longer one in my 34( auto parts guys have brought me the shorter arm and I always have them get the longer...might be wrong on some books....I'm away from my spare now, but I think the arm is around 5 inches long...if it's the shorter one I don't think it'll work--arm is more like 3 inches. Pull yours, check to make sure it's the right one, put a little grease where the line hits it and you should be good! Good luck.
