Guest 12lbsofbeans Posted October 11, 2002 Share Posted October 11, 2002 I searched I promise but can't seem to find the answers! How are people going about running a 3/8 fuel line from their gas tank. On a 78 the tank has 5/16 in (although I just read its a 3/8 outlet - is this true) and return line spouts, I believe. I know I can run up to a good filter then on the out side of the filter use a 3/8 or 6AN fitting and go from there forward. Is this ok, I'm talking about using the oil filter size FRAM style filter, it acts as a small resevoir also. Or I remeber someone using the fuel tank drain plug as a starting point, provided you have a clean tank is this good practice, if so what size and thread is that plug, 3/8 npt maybe? Also thoughs who have ran a 3/8 or 6an line from the pump forward what did you use? Hard line or braided flex and how did you run and mount it? I have a good filter, pump & regulator now I just need to upgrade the lines and I want to do it right the first time. Any help is appriciated.

jeromio Posted October 11, 2002 Share Posted October 11, 2002 I recommend aluminum line. Just make sure it is mounted nicely every few feet or so (if it vibrates it will fail over time). I started with steel line. Ugh. That was a nightmare. Too rigid. Broke my tubing bender. I think stainless braided line would be too expensive.

Guest heinera Posted October 13, 2002 Share Posted October 13, 2002 I used -8 stainless braided tubing from my stock 78 gas tank, to the filter, to the pump, to the fuel pressure regulator. The fittings and the line from summit was about 100 bucks. Its easy to route, and mount. Its tricky to cut, you need to use a high speed cutoff air tool. About $30 at wal mart. The -8 fit a little loose on the stock output of the tank, but tubing clamps snugged it right down. I don't think I will ever use hard line, stainless, steel, or aluminum to transfer liquid again. Its just to easy and cool looking to use stainless braided. Quote Link to comment Share on other sites More sharing options...
DavyZ Posted October 13, 2002 Share Posted October 13, 2002 The only problem with using the braided steel hose running the entire length is that many drag racing tracks want no more than 2 feet of braided steel maximum. Pity. I agree using braided steel is easier to mount and bend. Davy Quote Link to comment Share on other sites More sharing options...
fl327 Posted October 14, 2002 Share Posted October 14, 2002 some tracks wont let you race with out no more than 12inches of soft line, braided or not. but i havent had an official yet look under the car, just under the hood. Quote Link to comment Share on other sites More sharing options...
