Does anyone have a good source for locating part numbers for a 2001 suburban, 2500 6.0? I am trying to find a suitable replacement kit for the fuel lines (evap, return, supply) but can't find any via my normal method/sources of rock auto, amazon, 1a auto, etc. that seem compatible per the sites. The existing lines are on their last leg and a light tap away from rupture.
An example of the type of replacement/repair kit I am looking for is as follows: https://www.1aauto.com/chevy-gmc-sta...iABEgLjTfD_BwE

Thanks for any advice.
