        Does anyone have a parts breakdown or know what the P/N’s are for the o-rings in the fuel primer?  Mine is squirting more fuel on my hand than in the cylinders….

          Hi Bill ,

          If you have a stock primer it would be a small barrel Parker primer  ( I think it is a 401). The shaft seal is not an o ring but rather a band or ring type seal.  They used to be leather, then updated to rubber and the latest and best is a combo of rubber and teflon.

          You can get them ( small barrel Parker primer shaft seals) through Lance Aircraft in Dallas.  800-752-4005.

           

          Take careful note of the shaft (pump) position when you remove it to change the seal. Make sure it goes back in the same position and DO NOT move the brass valve located deep in the primer body.

            Thanks Sam!  I’m in Dallas, so I’ll swing by and see John and the mutts at Lance.  I appreciate the info and the tips!

            Thanks,

            Bill
