Re: 72 blazer ls swap

As for the fuel system I decided on trying the poly fuel lines after reading hemi43's thread. I bought a factory sending unit for the 87 blazer and cut off the flare fittings. Dorman sells a repair kit that has 2 12" lines with the quick connect ends. You can cut them to length then use a flaring block and swage to expand the pipe. Then brazed them together with 45% silver braze. Then added an Acdelco ep381 fuel pump that plugs right into the sending unit. I still need to find a fuel filter that has the quick connects. I think the early 2000s mustangs will work.
