Linda Posted January 24, 2018 Report Share Posted January 24, 2018 Does the mark on the fuel pump near the fitting always designate outflow? I thought it did. Thx Linda 1 Quote Link to comment
datzenmike Posted January 25, 2018 Report Share Posted January 25, 2018 Hi Linda, welcome to Ratsun. Good question. I think the body can be unscrewed from the base with the diaphragm and 'clocked' or rotated to move the positions on the inlet and outlet. Some castings look like there are at least three possible fitting locations if drilled and tapped but only two are used. I'd hate to say there is one position for all pumps. If the pump is off the engine hold thumb over one of the fittings and work the arm up and down. Suction or pressure? 1 Quote Link to comment
