Fuel line

[HP2]

Certainly the factory fuel lines were installed as one peice. Aftermarket fuel lines come in 25' coils so again, the opportunity to make them in one full length piece.  Aside from the leak potential of multi piece lines, is there any reason to stick with a one piece line over a multi piece line with couplers? Racing rules, corrosion, DMV constraints?

No good reason , other than leaks or loosening fittings , a small leak can reduce the effectiveness of the fuel pump to pull fuel in as air is far lighter to move .

Finelines. One piece sets and great prices. Don't mess with coils or line and fittings and leaks.  http://www.finelinesinc.com/dodgechallenger-1970_1974  check them out. I'm glad I did.

More fittings will add flow resistance/turbulence through the various fittings. Perhaps not enough to cause any fuel heating or volume to the engine problems however.

This isn't a restoration so I'm not required to use duplicates of the factory lines, especially with my fuel pump arrangement that alters the rear layout and engine bay routing and my non-traditional subframe connectors that may have an interference point or two with the factory line locations.  But, having said that, the Finelines prices are not too shabby looking and I could use two lines so one is a fuel return off my regulator. Might have to look at these more closely.

Just another option if your not concerned about originality ... I used PTFE line and fittings from here. http://www.frozenboost.com/stainless-steel-teflon-fuel-lines/?osCsid=890c7f7b62836a43cf34f83a2b0bf3fa

I bought stainless  hard line tubing locally bent it up and used the above link for connecting to various parts.
I used Swageloc stainless fittings on the tube to connect the tubing with the PTFE hose. Sourced them off E-Bay about $20 per fitting
I spent about $200 at frozenboost and did my car with a return line and a buddys  circle track car and still have parts left over.
I used 8-AN  and 1/2" tubing

I do have -6 ptfe hose for my flex connections, as well as alcohol compatible pump, filter, and regulator. The proliferation of E10 and the possibility of maybe running E85 in the future pushed me towards that decision. I suppose I could use it to run the length of the car but I like the look of the hardline lines and the ability to tuck them up into tight spots with a little bender work. But now I've getting some challenges with routing that does make the multi piece line appealing.
