TPI Fuel Line Help Needed
I installed 3/8" Feed and 1/4" return stainless steel lines that I bought before I decided to go with TPI and now realize I may have to change to 3/8" and 5/16" steel lines. The fuel tank is new with the original sending unit. Do should I switch to steel lines for the double flaring connections? What's should I use to connect from the frame rail lines to the fuel rail at the engine? I want to go with the fuel pump mounted on the tank crossmember with pre and post fuel fuel filters; steel lines inbetween? How should I connect to the fuel tank? I appreciate any help. Thanks!

Ok easy one first. From fuel tank to hard line just use FI rated rubber line and FI band clamps.
Now at the engine go to WWW.ANPlumbing.com and get the adaptors to go from a -6 flex line to those ports coming off the fuel rails. I believe they are 14mm and 16mm oring fittings.
Now from the flex line to the hard line mounted to the frame get the hard line adaptors they also sell for a -6 flex to the size line you're running.
On my El Camino I did years ago I made my own hard lines from rolls of line I got from Napa. I brought the fuel lines up the left side frame rail. Because crossing them under the motor from the original position to those manifold ports just didn't look to clean.
If those SS hard lines you bought will work for my 71 BB car I'll purchase them from you to offset your pain of having to buy them.

I ordered the pump from Summit Racing, but it's on backorder.
Thanks for the great info and the link. I needed someone to point me in the right direction
I kinda figured the stainless wasn't going to work. I purchases the stainless steel lines here http://www.classictube.com/ Let me know if they'll work for you.
