Has anyone found a way to replace the steel fuel lines with a flexible alternative?

 

All the fuel lines except the high pressure lines from IP to injectors, can be replaced with fuel hose, as they have less than 4lbs pressure, the engine consumes less than ten oz's per min on the hyway, so big lines are a waste of money..stock fuel pressure nominal is 1/2 lb, max is aprox 4. more than that applied to IP will adversely affect timing. at all RPMS.

 

Timing is not affected until 8psi of fuel pressure. I replaced all my steel lines with Cunifer and used 30r14 fuel hose from napa for all flex lines and connection in place of quick connect.
