I think you can find just the diaphragm for those $4.00 or a complete kit..------I know I have a few of those diaphragms on hand.----Ordered them 4 at a time.-----You may not find them for a 76 model listing.------Look under a much newer model !
Ok thx. I just took fuel pump apart. It was not right and dirty. I found a kit number from Leeroys ramblings. Of course like you said they don’t list one for 76 model. Thx again. I’ll keep you posted.
