Toller Posted January 16, 2020 Share Posted January 16, 2020 The hand primer pump on my 673C Thermodyne finally gave up the ghost while I was bleeding the fuel line. It's the type that's mounted to the fuel supply pump on the side of the fuel pump. The top unscrews and has maybe a couple of inches of travel. Does anyone have a part number or know of a good after market replacement? Thanks.

Rob Posted January 16, 2020 Share Posted January 16, 2020 PAI still has them available in the original style, but they are easily rebuildable for less than $20.00. EKT-2221 is a PAI number for a rebuild kit. Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

AZB755V8 Posted January 16, 2020 Share Posted January 16, 2020 New one's are on Ebay. Think I paid $20 with shipping, Bosch part not china junk. Ether old or new style Bosch will work.

Toller Posted January 17, 2020 Author Share Posted January 17, 2020 Thanks so much for both leads. I saw the Bosch online but wasn't sure about it. I may look at the rebuild kit as the way to go. Really appreciate the information! Quote Link to comment https://www.bigmacktrucks.com/topic/60576-hand-primer-pump/#findComment-440537 Share on other sites More sharing options...
