Ok… I was hoping…lol

 

To drop the tank , you’ll need a jack 4 safety stands, 2x2 foot square piece of 1/2 plywood, 15 mm socket 12” extension and a ratchet, 3/8 or 1/2 drive.

While the tank is down, change the in tank fuel pump, you just know it’s gonna fail after a couple of tanks of gas, why drop the tank twice?

Before you drop that tank double check the vapour and fuel lines

Will do. Thanks

 

I might have forgot about a screwdriver for the gas filler hose clamp, and a pair of pliers or tool for the fuel line disconnect fittings.

if its the fuel lines, you don’t need to drop the tank.

 

Oh, ok. Thanks again

 

Here is another possible source of a fuel odor. Take a look at your fuel fill tube for heavy rust. My old tube had very heavy rust where this bracket was welded. With a full tank, there was a strong fuel odor at the right rear. One evening, I was lucky to spot a few drops of fuel on the driveway. When I crawled under the car and looked up, there was still a small drip of fuel hanging off the fill tube. Must be a small pinhole in the heavy rust area. My fuel odor problem is gone.


There must be a small pinhole in the rusty area.

 

I think you’re correctly looking at a very good possibility of the rust eating that tube . I often wonder if a gas compatible hose can be used to connect those two pieces after you cut out the rusty piece.

 

I wonder how such a bad welding job gets past QC.

 

RTV? Silicone? Silicone is worthless for fuel leaks as the gas turns it into running goo. Silicone is a hazard to use on an engine, because excess seeps out and leaves loose "worms" that tend to fall off with time and go to the oil pump. If you use it wrong, excess comes out at all edges, AND, if its used to seal a gasket that has a hole/passage. it seeps into that hole, reducing the size. If its an oil hole, can you guess what COULD happen?

 

Hmm the seal from the factory for the oil pan and the engine upper and lower halves is a bead of sealant, possibly RTV or room temperature vulcanizing. A form of silicone. But it’s applied in a very precise manner.
