Bringing back a old topic here

I’m sure my sending unit is acting up

what is the best way to remove this

drop tank ?

 

What I did on my 72 Cutlass. May or may not apply to your car. But may help you?

Thank you.
i really don’t wanna drop the tank but I think there is a bad wire
i may cut a square on top of tank in the trunk and see if I can see anything

 

Yea, I considered your option. May or may not work. Dropping tank isn’t that bad of a project. Getting the fuel out is one of the biggest parts of it. Run it dry like I did, carry a gallon with you. Just enough to get you home. Then, the tank is just 10 pounds or so. I will encourage you to remove the tank, and check everything while in the area. Old rubber fuel and vent hoses likely need new ones.

If you do need to remove replace the sending unit, it will be difficult working through a hole in trunk. The locking rings on the sending units take something like a punch and hammer to turn them sometimes. Tough to do working through a hole.

well the fuel on mine is the easiest
my car has no stock set up
I have a electric fuel pump and the fuel line comes out of bottom of tank super easy to disconnect

I suspect all my vent lines are gone and I suspect that I have a bad ground wire as the fuel gauge is pegged at Max

Well decided to tackle this tonight

Sender wire connector on top of sending unit is bad. Not sure how that goes bad but

replaced it and now it works fine

 

That's some lazy, hack @$$ $hit, right there.

 

easy peasy

 

to be fair most cars have this accessible just by lifting carpet
Makes future work a breeze.

 

Lemme guess: the cut out piece is now held in with duct tape

 

no it’s not
it’s like a patch job on a floor. No different

 

A piece of carpet will do, but to be fair, duct tape will make future "work" a breeze . . .

 

no duct tape
proper patch with silicone will do

 

Ahh, the guys are having a little fun with this. I get it. Not what I would have done. But it did work for you. Clean up the cut lines all four sides. Make a 20 gauge patch 1” bigger all the way around. A few Sheetmetal screws…..Silicone will be hard to take apart if you wanna get back in. Some butyl tape would work great.

Maybe you can clarify for me? I thought you said that the fuel line was on bottom of tank? Have you abandoned the fuel lines in your picture? Just using fuel level part of the Sender?

 

yes. I have electric fuel pump. Not sure. Where the existing hoses go
