Glass Bowl AC Pump Thread Size

PostPost by: david.g.chapman » Thu Jul 30, 2015 6:46 pm

I have acquired an original AC pump for my twin cam, but now have to adapt it to my 5/16 inch fuel hose.

Can anyone confirm that the thread on the fuel ports are 1/2 inch - 20 UNF?

I am looking for some adaptors but no luck yet. If anyone has found some I would be grateful for a link.

Update - I have found a link! here it is if anyone is interested:

I just need a yes on the 1/2 inch UNF

Thanks again John,

I just got there myself - measuring female threads with my crude rulers was getting tricky, but I found a male bolt that screwed in - much easier to measure!

Cheers,

Dave.
