Hi Rod,
I had the same fuel line concern, I took my fuel line section off and down to fuel line, Hydraulic and fitting company. They made me a new fuel line to higher specs than original, I asked for higher heat resistance and burst pressure. It installed without a problem.
No problem on the fuel draining or anything like that.
The name of the company was Pirtex, Fluid Transfer Solutions. I believe this is a national chain and this one is a local distributor in the Sacramento area.
Good Luck,
Bill
