Re: Fuel Tank sending unit screw problem more
I have been testing my fuel tank, slight leak from the sending unit, so I replaced it. Tested again and noticed a leak from one of the sending unit fitting screw. I tried just to tighten it the slightest bit, but the thread in the tank stripped out.

larger screw and marine/re sealant. done
The sending unit should have two wires coming out of it. They are non polarity sensitive. This means you can hook them up any old way and they will work. more
you have to have ground get to the tank. you cant assume the tank is grounded by its mounts.
C. if none of these test work, go to the back of the gage and check connections, S to G should cause gage to peg, if it doesn't, see if the gage is getting power at the ign terminal. if the gage is getting power and jumping sender to ground on the gage does not cause gage to peg, you have a bad gage.
Re: Gas tank sending unit wiring diagram help
If the bolts or screws are extremely stuck. Use some penetrating oil liberally in order to get them turning. It is also important that you clean the top of the sender before working on it or removing it. This way we are keeping dirt and other stuff from getting down into the fuel tank. here
Using a piece of wire, you can run from the ground on the battery to the back of the gauge. This will confirm you have a good ground.
Taking a stick, a tape measure or something else, we want to measure the distance to the bottom of the fuel tank to the top. Leaving off about one inch from that number, we now know what size of a sender to buy. here
Leave a comment below and tell us how your fuel gauge issue turned out! Or if you would like to ask us some questions, we’ll be glad to help you get up and going!
After removing the fuel sender, let’s check it before putting in a new one. Connect a meter to the two wires on the sender. With the meter in the continuity feature, slowly run the float from the bottom towards the top. here
Connect the jumper wire to the ignition switch and the terminal on the back of the fuel gauge, then turn the vehicle on. If the gauge now works, replace the defective wiring between the gauge and the ignition switch. here
There are two main components to the fuel gauge system: the sender unit that measures the amount of fuel in the tank, and the gauge itself that displays the amount of fuel to the driver. When the gauge, the sender unit, or the required wiring between them do not function correctly, the fuel gauge may read falsely or simply not function at all. There are some simple tests you can do to see if your fuel gauge is working.
Ground the gauge by soldering or clipping one end of the jumper wire onto the gauge's grounding terminal and the other end onto a clean contact point on the vehicle's frame, then turn the vehicle on. If the gauge starts working, replace the defective fuel gauge grounding wire. here
Ground the sender unit with the jumper wire using the method described in the previous step. The sender unit can be grounded by attaching the jumper wire to the exterior of the fuel tank or the vehicle's frame. Replace the sender unit's grounding wire if the gauge begins to function.
Turn the ignition on and off several times in succession and note if the needle moves at all. If there is no movement, check the fuse. The fuse panel may be located under the hood or under the dashboard. Each fuse should be labeled with an amperage rating and a number or series of letters indicating which circuit the fuse protects. Reference your service manual to determine where your fuse panel is located and which fuse controls the fuel gauge system. Replace the fuse if it is bad, making sure that the replacement fuse is the correct amperage rating. here
