Fuel line questions
-
Getting ready to replace the fuel lines on my Hornet and I was wondering what size line to use. Gonna go with stainless steel line all the way. I think it currently uses 5/16. Would there be any problems if I over sized it to 3/8? I'm going to run the AMC mechanical fuel pump and wasn't sure if the over sized tubing would affect the performance of the pump.
Also, need to reline the inside of the fuel tank. Is POR-15 the way to go? Has anyone had expirience with any of the other products out there?1953 Hornet sedan Twin-H

If you don't mind my asking, why the larger size fuel line? I don't know of anyone who has a fuel starving issue out here...... Existing size is 5/16". That is also the size for the AMC fuel pump as well.

the line I'm looking at (through a supplier at work) doesn't come in 5/16. Of course I probably don't NEED the seamless stainless steel, just thought it would look better and last longer. Fittings to go from the 3/8 to 5/16 are available through the same supplier, so the adaptation to the pump is not an issue. I will keep the 5/16 from the pump to the carbs in order to keep the pressure up. Also going to install a check valve between the pump and the carbs with a 1/3 PSI cracking pressure to stop the backflow problem through the pump I'm having now.1953 Hornet sedan Twin-H

It's your choice of course what to use. Just a couple of points - stainless steel is harder to bend, and is subject to work-hardening if subject to vibration. 5/16 is perfectly adequate, but there is no reason not to go larger. Consider how long the original steel line lasted, and how long you need to live to see if it is going to be worth while changing! Good luck,

The last line of the above has to be the best reason for using steel lines that I've ever heard.
