Stainless steel fuel lines

Post by eastbaysolo_73 »

Sup fellas I'm getting ready to purchase some 3/8 stainless steel tubing fuel lines for my KA-T swap. My questions to you all is how manny feet should I buy?
Ebay has a deal on 20" 3/8 SS line for $51.00 plus free shipping. Not sure if thats enough for what I need. If you have better source to purchase the tubing from please feel free to chime in.

Thanks

510 wheelbase is ~8', so if you want supply and return and extra to get it from tank height down, under, and then back up to intake height, 20' doesn't seem like enough. If you're doing two lines and wanting to mirror the factory under-floor routing, 30' is probably closer to the mark.

Thanks man very much appreciated. I have a 15 gallon fuel cell so it won't need to go that high. I will see if I can find something longer then.

when going stainless, I have to ask what grade of stainless line is it? The reason I ask is that forming stainless tubing is quite a bit tougher than steel lines, so care needs to be taken on the type of forming tooling you use and the type of fittings you'll utilize.

On my car I went 316L, as it's a bit more forgiving on teaching forming get side. I also utilized JIC fittings because the tubing is asked to do less to make the seal.

Just some thoughts.

Not sure what it is but I did just ask the seller what gauge it is.. Thanks for the heads up I wish I had known this before I bought it. LOL
