Trooper T2 Fuel Tank Sensor

Need a source for replacement of fuel tank guage sensor.

Try Jegs or Summit Racing and replace with a good aftermarket universal unit. You will have to change the sending unit and dash gauge both. The Joyner units are crap.

Napa Auto Parts also has a replacement that is universal. I looked at one but have not ordered or replaced. Seems like it is a good unit. I believe it is a VDO unit. I actually have an extra complete stock sending unit but it is for the deeper fuel tank. I have the tank that is under the rear seat so this one is too long.

If it's one with a float on the end of a wire, You can cut and bend the wire to work in the range that you need. I used one out of a Dodge pickup that way and it worked great. Was able to use the same stock gauge.

The only thing you need to worry about are the ohms. Not sure what the stock gauge is but there is a range on the Napa one. And yes it can be adapted to fit any tank.

Here's the components in the sender, the switches are reed switches activated by a magnetic float. I've repaired a few of them for myself and other members. Replaced mine with a capacitive sender unit that I built and need to pull out and see why it's not working, in the mean time, I just make sure it's full at the beginning of each outing.

My capacitive gauge quit working so I went back to doing the way Joyner did sort of, instead of 4 reed switches, I used 10, now when the tank is full, the needle is on the white line, then 7/8, then 3/4 in the middle of the upper blue, then 5/8, then 1/2 on the middle white line, the 3/8, then 1/4 in the middle of the lower blue, then 1/8, the empty on the while line, the 1/2R in the middle of the red, then 0 on the bottom white line. The picture shows the old and the new.

I am going to use the old farm tractor method. Straight down filler tube, take off the cap, look inside or use a measuring stick & fill her up when she needs it.

Has anyone had a fuel gauge sender unit fail after I repaired it? I changed mine and found the epoxy swelled and caused the glass reed switch to brake and fail.

I'm trying to figure out if the fuel level sensor tube is 200mm or 190mm. Does anyone know? I need to buy a replacement.

Kinarfi · June 30, 2015

What are you driving? What's the fuel gauge for?

what year?

I think I still have my original sender of 5 or 6 reed switches, Or you could build one like mine. It has 14 reed switches and 16 LEDs, the 1st & 16th are always on 2 thru 4 are red, nearly empty, 5 thru 7 are yellow, less than half, and the last 6 are green, good to go. The brass tube is in the center of the tank and sealed so the circuit board & reed switches are dry. Down side is you have 15 wires running from gauge to sender.

there is a DLA valve, page 109, that lets air past the butter fly, sound like it failed, there is also a idle adjustment screw, page 49, find it, use it,
