What's the pressure in the rails at the highest point (strongest)?



I'm curious what type of fuel line I should be using, for some reason there's a huge price difference between 50 psi line and 100 psi line.



I was under the impression FC N/As pressure was around 40 psi.. Not to mention is has a pulse dampener.. That would take stress away from the line wouldn't it? I dunno whatever..



Help me out here.. 50 psi line or 100?

 

~42 psi at atmospheric pressure, and about 28 PSI at idle.

 

50 psi line it is then..



I think I used 50 psi line on the car already but I couldn't remember (I asked about this a long time ago thats how I got the 40 figure).



Thanks
