I don't doubt that aluminum might work fine for 90% of the cars out there. I just know my luck. I have to make stuff as bullet-proof as I can make it. I'm also not THAT worried about the added expense of something if I only have to do it once.

I ran an FMU setup on my ride for 7 years that would spike the fuel pressure beyond 150psi when in boost. In the mean time I did put another 50K miles on it in that configuration. That said - I've always worried about a fire for obvious reasons. I was doing it all wrong, but it DID manage to make 700hp thru a 1/4 fuel line. LOL

I'm working to pull it back from the brink of self-destruction with smarter choices.
