Anyone know an idea on what the fuel pressure is at WOT, I'm deciding if I need to run ss lines from the fuel tank to the rails or otherwise use a earl's compression nut fitting to the feed hardline...supposely Earl's only handles up to 50psi, but I've read otherwise

 

fuel pressure should be 43.5 psi + whatever boost you are running. so if you are running 20psi of boost. it would be 63.5psi of fuel pressure total

 

If it is base fuel pressure + boost pressure.

If you are doing a fuel system, you could clamp the AN line to the factory hard line. I have been doing this for years. There are nice-looking hose clamps available:

Great! Sounds easy enough
