Well Here is a Little Pictorial of some Rust I ran into When I Removed the Tank of the Duster Last week. It had a small leak at the top of the tank only when it was above 3/4 full - Then the Gas gauge started to read 1/4 all of the time.. So it was time to Take the tank down.
Got a new tank and sending unit from rock auto..
This is probably the 3rd Tank I have had on the car... It was Repaired with lead and Sealed inside probably 8 or so years ago... I "painted it with Grease" all over and Replaced the Stock water holding Gas tank Pad with Old sections of cut up intertube..
Due to the Crappy placement / design of the Tank and The supporting hardware the Left Upper side of the tank gets a lot of splash and wash from the road , and it will sit on top of the tank.. causing rust.
This car has 201,000 Miles on it now So my first major Patch goes in the trunk on the 32 year old car that gets a lot of salt.. I dont think there are too many others out there using f bodies as daily drivers for 16 years in Salty weather...
Here are pics of Damage, Patch And repair..
Uh Oh... RUST.. I have a full Trunk mat from a mirada so I never see the trunk floor of my car at all.. :-0:shock:
Worst Part about this is that the Rust ate the Upper Tank mount area.. I had an old F body Trunk floor in the Shed....
Cut out a Patch Panel From the old trunk floor in the shed.
Comparison... Cut out Piece vs New patch Piece..
Hole in floor...
On the Replacement Piece, I welded up the "crap Catcher" that Ma Mopar made that Funnels dirt, grime, saltwater right above your gas tank..
Repair Complete..
