I should have it running this weekend. I got my aluminium fuel line and all of the fittings. I will up pics when I am done.

Update It has been running for 4000 miles and with the exception of sucking some air in to the racor 1000fh filter I have had no Issues.

Also one thing I did different than when I started was I am now running the return line back into the fuel line right berfore the filter, this way I do not waste the heated fuel. I am not heating the tank at all. it has been in the low 30's here and I have no issue with the temp. it takes me about 5mile to get up to temp.


thanks for all of the help

A problem with copper that nobody has mentioned is that it work hardens. With repeated cyclic stress, i.e. bending or vibration, it gets brittle and cracks. It's a physical property of copper and why it's not legal to use as brake line. It will enventually break but would, however prove the concept. You say got some aluminum tube. That's good. You might be able to run it inside black iron pipe. I like the pipe-in-a-pipe idea for the run between the tank and the engine bay. A pin hole in the collant hose under the vehicle is all you need to ruin your day. It's worth the study.
