b422 Posted September 19, 2018 Share Posted September 19, 2018 Some one put on an aftermarket 12v fuel pump. Is there a company out there that sells rebuild kits for the original pump?

Firemack Posted September 19, 2018 Share Posted September 19, 2018 I have a 464 also in a B75 Firetruck- I sent mine to Kanter Auto Restoration http://www.kanterrestoration.com/ They rebuilt mine like new in about 3 days cost $84 but that was a few years ago. They normally do AC Fuel Pumps for chevy's etc. Just call them and let them it is a regular type AC Fuel pump and you know another guy that had a few rebuilt by them and are still working.

Maddog13407 Posted September 21, 2018 Share Posted September 21, 2018 interesting. B422 would have a size 3 bellhousing originally and a baby quad or duplex 77 series. someone would have to change motor mounts and all to put a 464 in there. never amazes me how much wrenching went on with these old trucks Quote Link to comment https://www.bigmacktrucks.com/topic/54320-en464-fuel-pump/#findComment-406372 Share on other sites More sharing options...
b422 Posted September 21, 2018 Author Share Posted September 21, 2018 yes according to the build sheet from mack museum it came with a en438. so you are correct some one had to put in some time to change the engine out. I took off the fuel pump and pulled a number from it. Its an AC 855573 Quote Link to comment https://www.bigmacktrucks.com/topic/54320-en464-fuel-pump/#findComment-406417 Share on other sites More sharing options...

JasonGottschalk Posted March 16, 2020 Share Posted March 16, 2020 I’m looking for information on fuel pump system on my b42 with 401. The pump is pumping but doesn’t supply enough to the carb and loses prime.

j hancock Posted March 16, 2020 Share Posted March 16, 2020 Yup, needs to be rebuilt. You can contact Kanter or Daytona. The links are above. If they can't help, they will be able to suggest alternative shops. A google search for fuel pump rebuilders will get you a list of folks also. Quote JimIt doesn't cost anything to pay attention.

They like to stick when getting old. I just rebuilt both mine last year. Found everything online easily with the pump number for about $25.00 each kit.

AJ34 Posted May 3, 2020 Share Posted May 3, 2020 I have ordered my rebuild kit for my fuel pump but can’t figure out how to get the old diaphragm apart to but the new one in. Has anyone ran into this and can point me in the right direction.
