I'm sure you will have problems finding "aluminum" line locally, i know i couldn't, the only other bet is "copper" at Home Depot or Lowe's, its a bit pricey & hard to bend for tight corners around the frame rail, the aluminum is the easiest & not as likely to kink.

Once the hard lines been re-placed (along with the short rubber hose at the crossmember) & by ANY chance its still having issues, it'll make it alot easier to narrow it down.

When i disconnect my hard line from the pump, it'll poor gas instintly & drain the tank, Oh but i'm running a fuel cell .

Let us know how it works out!!
