Hey guys, Im getting ready to drop my +-430hp motor into my FD (LSx too hard to find over here) and my previous motor was also 428hp.

Im running a 255lb walbro pump w/press. regulator. Stock injectors cleaned and serviced.

The fuel lines running from the pump to the rails, should they still be fine, are they going to be 'just good enough', or should I get some higher pressure lines?
Does anybody know what the stock FD fuel lines are rated at?

Thanks in advance,
James

 

They will be fine. We've ran them to well over 600whp.

Assuming they're the same as the usual high pressure fuel hose, it's typically rated to 12 bar.
