Fuel pump module question What does the black littlle line

Post by tomtk »

off the pump inside the module do? My original module broadcast code SGH had one but the replament number FG0070 from Delphi did not.

The new module says it has improved materials for the gauge sensor and an updated wiring connector.

On the Dephi site in a TSB there they show the stock wiring harness failing inside the tanks.

So just where is NHTSA on this one this is a safety issue GM should be changing out those connectors for free
