Hello, I have a niche old AC fuel pump and looking for a repair kit. The pump is in good condition, the valves are clean the electric look good and working only the rubber is like chewing gum. Knows anyone how I can get the parts?
I had one several years ago, same problem. The GM dealer had no record of such a pump. I believe it was built for AC by Dupree. No idea if repair parts are or were available.

They were sold through A/C Delco dealers. I used to use them on my '51 Merc. The 6 volt version is an EP-11. A/C #. don't know the # for the 12 volt one. both are no longer available, and have been discontinued. all of mine seemed to suffer from a problem where once the preset pressure was reached it would not shut off and began flooding the pump and leaking out of all the gasket areas . bad ju ju for a car sitting idling. happened with 2 different pumps. could have been bad. that being said the first one lasted over 15 years. No ethenol fuel here so that was not the cause. I did find a few kits on the internet about 5-10 years ago that was just the bellows ( all the rubber stuff) but I can not remember who I got them from. I have not been able to find anyone who rebuilds them and 6 volt ones are no longer produced. I do not know if the 12 volt ones are or not. I wish I could find a 6 volt pump like these ( I refer to them as pulse type pumps, because you can hear them pulseating until the float bowl fills and then shuts off. the EP-11 6 volt pump is/was a low press. pump@4psi max). I am now using an Airtex pump that basically runs as long as the switch is on. It is a low press. pump also, but the quality ****s, and they don't last long
Yes the bellow is the problem all other parts are no problem It is sad that there are no parts because it is a nice piece. I got two Autopflux pumps from the 30thys and there bellow is from stainless, they last forever
