Fuel level sender unit replacement?

Postby Gary. » 15 Aug 2017, 17:24

Once again, here I am asking questions! I've checked the Wiki and there is no info on replacing the fuel level sender.

Mine has bailed out, was erroneous anyway! I tried disconnecting the plug and socket and ended up ripping the connections from the sender unit - whoops! Should the white two pin plug thing come apart? I just cannot budge it.

I'll pick up a replacement sender from brickwerks, but can anybody advise on anything else that I might as well sort out whilst doing the job?

You will of course need a new seal and the two horseshoe stud plates that secure the sender into the tank.

Are there just two plates to the outside? Mine seem pretty clean, so do I need to replace?

The two plates are on the inside of the tank...
I didnt replace mine as they were in good condition (the diesel kept them from rusting), the threads (that are on the outside of the tank) did need a good clean up though.
The seals are worth replacing no matter their condition as they are cheap!

I still need to set mine up properly... thanks for reminding me!

I have done it a couple of times, replacing the sender unit itself is not too bad a job providing you clean and lubrication everything before you start. The biggest problem I had was with the electrics, getting the plug off, cleaning and refitting it in situ is a nightmare. the second time I did it one of the pins fom the old sender broke off and was stuck in the connector. I ended up having to cut the wires and remove the conector to get the pin out. I fitted the conection to the sender on the bench as it was easier and rejoined them wires once everything was back together.

That connection is a complete sod, it just will not come apart. I believe I will also be cutting the wires and connecting on a bench!
