I have never done it, but sounds like you might have the lines mixed up!

There should be three: feed, return, vent/charcoal canister

^That's how it is on mine...

I would assume if it was FI it would be close to the same!

They all have 3 lines.When I put mine back together I had the feed and returns backwards.I at least remembered to test the lines but turning out my fuel pump and have a catch bottle on the feed line.Can't really mess up the fuel lines when theres only 3.

how much gas u got in the tank?The Maz tanks have baffles in them to keep fuel from sloshing around and to keep a supply of fuel at the fuel pump pickup point.if the baffles are not in the same place,the fuel pump wont pick up as it should.u said u have gas at the FI rails but is it at the correct pressure?should be at 13-15 psi for the injectors to function as they should.I swapped tanks on a 2600i once,tried to put a 91 tank in a 90 truck and the damn thing wouldnt run because the baffles were differnt and it was fuel starved.bj

snoplow, i have a 2600i, the &quot;i&quot; means fuel injected
