BigT Posted March 5, 2021 Share Posted March 5, 2021 I am attempting to restore an old fire engine that hasn't been on the road for a few years. It's a gas inline 6 thermodyne. I had it running for a while but the original dual chamber fuel pump is toast. I've ordered a few other pumps claiming to be compatible, but unfortunately would not line up internally. At this point I'm wasting time and money on "trying on" different pumps. So I'm curious would I be able to install an electric pump and pressure regulator instead of searching for another mechanical pump, if so what would ideal psi be?

yarnall Posted March 6, 2021 Share Posted March 6, 2021 I put this a Napa 12v fuel pump on several of my trucks including my 1947 85LS. It works great without a pressure regulator. https://www.napaonline.com/en/p/CFPB0110E?cid=paidsearch_shopping_dcoe_google&campaign=GSC-Fuel-Emissions&campaign_id=10951730297&adgroup_id=113117085528&adtype=pla&gclid=EAIaIQobChMIit65676a7wIVxgeICR3ewQ4NEAQYFCABEgJmNPD_BwE& mike 1 Quote Link to comment https://www.bigmacktrucks.com/topic/66145-1954-b-series-fire-engine-fuel-pump/#findComment-470060 Share on other sites More sharing options...

609albert Posted March 7, 2021 Share Posted March 7, 2021 I assume your gas tank is in the rear between the frame rails, I previously had a 47 mack pumper that the tank was mounted above the fire pump, that on had a cheap electric pump did not last long.

1958 F.W.D. Posted March 7, 2021 Share Posted March 7, 2021 Don't forget to only use non-ethanol gasoline if you are able to.
