100% new sending unit? no blockages in the tank? Follow the wires all the way to the dash to make sure they are not exposed or cut

There is a exposes wire that has a cut in the back but its not touching anything so i figured it wasnt my problem

Not sure exactly what that is but no exposed wire is good, get some electrical tape and tape that thing up. One thing you can do is to drop the tank again and pull out the sending unit, while its still connected and turn the key to the on position and move the sensor all the way up and see what it reads then drop it all the way down and see if it is reading full and empty, if it is then you know that there is an issue inside the tank somehwere, maybe the float isn't floating enough or something, maybe there is something stopping it from getting its full movement

I dont think it is a float device i believe it works off pressure

shamrock81887 · October 16th, 2011, 12:40 PM

And that wire runs to the sending unit qnd another spot on the tank im unsure what it is

91cobra5.0 · October 16th, 2011, 12:41 PM

That is the pump hanger the float is a seperate device in the center of the tank

shamrock81887 · October 16th, 2011, 12:50 PM

I wondered what that is maybe that needs replacing

shamrock81887 · October 16th, 2011, 12:54 PM

Dammit i just waisted money i looked up sending unit n i got that i needed to replace my fuel level sending unit uggggggg thanks bud im off to autozone

shamrock81887 · October 16th, 2011, 01:54 PM

Thats sum messed up shit i swear they should have these items seperated under different names theyare all listed as sending unit i think by replacing the pump though it fixed my idle hang issue beforewhen i revved my motor when it came back down it would hang at a grand for a sec now it doesnt hopefully my idle surge will go away too( which only happens in rainy conditions) maybe my pump was going bad who knows
