Problems with the engine

[Richard RV]

It was mentioned several times that the fuel lines should be replaced. Note that if you do not drop the tanks and replace the lines all the way to the pickups, you are NOT replacing the fuel lines. When I dropped my tanks, I replaced the rubber with steel lines, and bent them downwards at the edge of the tank so I can easily connect new rubber to them. This procedure is outlined in a GMCMI presentation by Emory Stora. See: https://www.gmcmi.com/wp-content/uploads/2013/02/In_tank_Fuel_Pump_Presentation.pdf

Emery was a treasure - a tremendous source of GMC "been there done that" knowledge.

Going down the rabbit hole of his postings on the original forum and the GMC photo site is never wasted time and highly recommended.
