Beefcake35 Posted September 26, 2022 Share Posted September 26, 2022 HI All, I was wondering if someone knew the part number for a fuel pump for my 1949 buick special straight 8. Started it up today and gas was pouring out of it. Cant seem to find a pic that looks like mine. Can you just put in a 6 Volt electronic fuel pump? Thanks in advance!

buick looks fine for 39 Posted September 27, 2022 Share Posted September 27, 2022 The above picture is of a correct 39 special fuel pump and with a repair kit from Bob's Automobilia etc they're easy to repair. It's advisable to get a modern kit with a neoprene diaphragm which is resistant to ethanol in current fuels. It's also not a bad idea to install an electric fuel pump rated at 3 or preferably 4 psi. Modern fuel has volatile light components which make them better suited for fuel injected cars. Unfortunately, the light light components in modern fuels make older carburetor cars susceptible to vapor lock. I can post the part number for a 39 mechanical fuel pump and a suitable electric fuel pump is you need it. Thanks Leif Link to comment Share on other sites More sharing options...
Beefcake35 Posted September 27, 2022 Author Share Posted September 27, 2022 Thank you Leif! I wonder if mine has been replaced because it looks quite a bit different. I am going to try to get it pulled this week. The pump you have the pic of... is that the straight 8? Thanks! Link to comment Share on other sites More sharing options...
Beefcake35 Posted September 27, 2022 Author Share Posted September 27, 2022 I found one that looks close but the gas connectors are just a little off. I was told the pump for mine should be a 504 but cant really find anything for that. Here is a pic of one off ebay and mine. thoughts if its the right one?
