what's the thought on using steel tubing for gas line ? I have fuel injection rated line running from the tank to the pump and out to the Sniper EFI . its at 58 psi and return line back to tank . I have never had a line fail before but ? The lines are against the firewall and about 6" from the headers and engine, the temp at headers is 350+- (idle).temp at lines and fuel line was 130. Maybe some shielding would help ease my mind. Anybody run just fuel hose for their whole system ? I had aluminum line but it seemed to light and cracking was a thought.
