DollyDodge Posted June 3, 2011 Report Posted June 3, 2011 Does anybody have a comparison on the AIRTEX Part # 587/AIRTEX Part # 9543 (the number used depends on the engine number) fuel pumps versus the CARTER Part # M2091 for the B-2-C trucks. Is Airtex or Carter a higher quality or are they similar in quality? My rebuilt pump is leaking heavily around the rocker arm pin. The kit manufacturer had a couple fixes for me to try, which I will do, but I think I want a new one around for a back up. Quote
NiftyFifty Posted June 4, 2011 Report Posted June 4, 2011 The price I got for a mechanical new pump I was able to buy a new electric pump at 1/2 the price...and now with my idustrial motor it's already got the cover plate for the pump hole on it. I haven't hear anything good about carter pumps in awhile from the shop I used to work at...we stopped using them even when I was there, but once inawhile their all you can get for old applications around here, but cause a lot of headaches Quote
John-T-53 Posted June 4, 2011 Report Posted June 4, 2011 Is it just leaking oil from the pin hole? The Airtex 9543 number sounds familiar. I got a Carter pump for my rig, mainly because that's what Nappa could get, and I trust it very much...so far, so good. Quote
Frank Ollian Posted June 4, 2011 Report Posted June 4, 2011 I just got an Airtex 587 at Autozone for 48.99. I think the two Airtex numbers are the same pump, just clocked different. My opinion is the Carter is a better pump if you can find one. Quote
DollyDodge Posted June 4, 2011 Author Report Posted June 4, 2011 Thanks all, John T, yes it is just leaking around the pin hole. the guy I bought it from said to carefully use a hammer and peen the hole smaller. The pump that was on my truck has a pin with a clip on each end, he told me to get small O rings and put them under the clip and that also helps Quote
Dave72dt Posted June 7, 2011 Report Posted June 7, 2011 Those are bandaid fixes. Peening them will move a very small and thin amount of metal back into the hole. If you just got it, take it back. It'll last about as long as the warranty. Quote
Dave72dt Posted June 7, 2011 Report Posted June 7, 2011 Those are bandaid fixes. Peening them will move a very small and thin amount of metal back into the hole. You might be better off removing the pin and fiting it with bushings so the pin fits snugly. Quote

DollyDodge Posted June 8, 2011 Author Report Posted June 8, 2011 No, you missunderstand, it is my old pump with a rebuild kit I installed. Quote
Dave72dt Posted June 8, 2011 Report Posted June 8, 2011 Yes, understand it's your old pump with a kit. Just suggesting a way that may fix it more permanently than peening. Oh, sorry about the double post. didn't intend to repeat myself. Quote
John-T-53 Posted June 9, 2011 Report Posted June 9, 2011 You could also slide the pin over, clean it, then coat the end of it and the inside of the hole with RTV or permatex No.2, then slide it back (and peen it). Quote
DollyDodge Posted June 10, 2011 Author Report Posted June 10, 2011 thanks to everyone. I somehow missed the bushing recommendation when I commented on that email. That sounds like a good idea. Quote
DollyDodge Posted July 14, 2011 Author Report Posted July 14, 2011 I got my new Carter fuel pump from Rock auto and it works great and doesn't leak. Yippie. For years when I was driving the truck inthe 70s I thought it had an engine leak, I never figured out the oil was coming from the pin in the fuel pump. With the new pump there is no oil leak. It use to be that the bottom of the engine, front axles, etc were always oily. This is really nice. The new pump is very similar to the old one. I also redid the fuel line. The blue goop around the pin on the new pump probably wasn't required, but I thought for the sake of it while I had the new pump out I would cover the ends of the pin just to make sure it didn't leak there so I could tell for certain where the leaks were coming from and with the new pump there isn't any leak any where.

Todd B Posted July 14, 2011 Report Posted July 14, 2011 I had 2 different trucks wih new Carter pumps on. I had problems with both of them. The Napa guy said it was the new gas eating the parts inside. I am not sure if he is right or wrong but I went through 2 pumps on each truck after about 6 monthes of use. I ended up putting Electric pumps on and I have not had a problem since (knock on wood). Quote
DollyDodge Posted July 14, 2011 Author Report Posted July 14, 2011 Just have to wait and see. I know the quy that I got the parts for the old pump rebuild also said new pumps have those kinds of problems. But we put a new pump on the 49 HA PH and it has been fine for over a year. So I will wait and see. Quote
Don G 1947 Posted July 16, 2011 Report Posted July 16, 2011 Dolly, Just been down that road. Rebuilt the pump with a kit from Antique Auto Parts Cellar and it leaked oil from the pin that holds the rocker arm. Took it apart and miked the shaft then called the folks there and asked if they had a larger diameter pin. They sent me one that was .0015" larger than I had and that appears to be doing the trick. Permatex did NOT work and neither did the "O" rings because there was not enough room for the rings. The tech at the parts place said another option is to thoroughly clean the outside of the housing and the ends of pin and use a little JB Weld to seal it up. He said it will seal it nicely and come off by hitting the side of the pin. Don Quote
DollyDodge Posted July 18, 2011 Author Report Posted July 18, 2011 I got my kit from the same place. I don't know why I didn't think of the larger pin option. I will try that next. For now the Carter is working well. Later Quote
