tilynb61 Posted July 26, 2020 Share Posted July 26, 2020 Hand primer leaking on my 63 END673. So to get home I bypassed it, line from tank directly to secondary fuel filter inlet. Truck ran for about 5 minutes, quit on the side of the road. Put it back the way it was, started right up, still leaking of course. Am I missing something on the fuel system flow? Thanks Quote Link to comment Share on other sites More sharing options...
KKERGALL Posted July 26, 2020 Share Posted July 26, 2020 There is a copper sealing washer on the pump. Not sure where your leak is ? 318GC17C pretty sure P/N# for pump. Quote Link to comment Share on other sites More sharing options...
tilynb61 Posted July 27, 2020 Author Share Posted July 27, 2020 Found out by routing around it to get it home I also was taking out the pump to supply the engine. I should have figured that but on the side of the road it didn't register Quote Link to comment Share on other sites More sharing options...
Freightrain Posted July 27, 2020 Share Posted July 27, 2020 (edited) Yes, the hand pump is mounted to the transfer pump. I replaced the transfer pump on my 237 after I got it running. I'm trying to recall by poor memory that the hand primer just screws down into the transfer pump? Have to look at mine tonight to recall. Is it leaking at that joint?

tilynb61 Posted July 27, 2020 Author Share Posted July 27, 2020 Thanks for the help. I haven't had a chance to look at it closely yet. Pretty good drip. Quote Link to comment Share on other sites More sharing options...

Have to look at mine tonight to recall. Is it leaking at that joint? If it is like the one I had, then, yes, it just screws into the pump. I got a replacement one from some 3rd party, but it leaked around the threads. I found a shop which had seal kits for the original. So, I took the original apart and put new seals in it. That fixed it. In fact, I may still have one spare set of seals in the top of the tool box... Quote "Eagles may soar, but weasels don't get sucked into jet engines."

tilynb61 Posted July 31, 2020 Author Share Posted July 31, 2020 If you had a pn of the kit that would help me out a lot Quote Link to comment Share on other sites More sharing options...
davehummell Posted July 31, 2020 Share Posted July 31, 2020 I got one for the old engine right from the injection shop that I had checking the injectors I think I paid around 30.00 dollars. Quote Link to comment Share on other sites More sharing options...
Milaca Posted August 3, 2020 Share Posted August 3, 2020 tilynb61, did you ever sell your 1964 B755? If so, where did it go to? Otherwise, I may be interested in it if you still have it. Quote Link to comment Share on other sites More sharing options...
doubleclutchinweasel Posted August 5, 2020 Share Posted August 5, 2020 Not sure if you ever got this fixed. Here are the seals I got for my old R. There’s a quad ring, an o-ring, and a copper washer. Got these from City Diesel in Knoxville, Tennessee. Was pretty easy to fix. Quote "Eagles may soar, but weasels don't get sucked into jet engines."
