if its a 55 any y pump will fit.your block should have special mains with 3 in bolts.

Thanks for reply, but dont think thats right.

If it's like the 239, an Airtex 4070 is what I use.

a fellow gave me one of these blocks about 15 years ago.untill then i thought 55 trucks were 272.these were CEBY blocks.they were the only true truck blocks,that is the only ones that were different than car blocks.there was a ceby  car block as well but it didnt have special mains just heavy trucks.the caps were 1/8 inch higher with 3 in bolts.i could see no difference in the fuel pump.these blocks were used to make 272s as well.

Does the pump look like this. According to my Carter pump book the 55 F600 with a 256 engine takes a M3150 pump which is the HD model for the Carter M3528

The 279 engine took a M3022 pump .

Just a note regarding the CEBY blocks. I have one of those and it came in my '56 Mercury M100. According to John Mummert's chart it is a cast in Canada Export block. 256-272. Thanks

Dennis, marv, thanks, i,m trying to ascertain if the 239 was same as 256 pump, and hence different to 272/292/312/, i am trying to find out for person over here. i think the 239 pump has straight arm? but not too sure. regards bill.

239 has a straight arm. If you google airtex 4070, you can see a picture of it .
