Faulty fuel gauge, sender fix.

A couple of pics and info on how to fix a faulty fuel gauge, normally a bad earth if the fuel gauge isn't working properly, using the fuel sender with a new earth wire.
Find the hatch, its about a metre behind the drivers seat, Unscrew and take off.(mines under my new floor, glad i left access

)

Unlpug the wire loom, take a new wire (earth) fit a ring on one end,
and fix under one of the screws holding the fuel sender, give it a bit of a wire brush clean first.

Then push the other end (bare wire) into the plug (the one with the black wire) then re-attach the plug onto the sender unit.(i also put a bit of wax-oil over the ring terminal to keep it from rusting)

When done, just put everything back.
You can do the earth fix from underneath the bongo, This may be the only way if you have no access from above.

When ours went wonky I scraped to bare metal round one of the holes in the tank rim, soldered a couple of eyes onto a wire, bolted through the hole in the tank rim and connected the other end to a bolt on the chassis near the under the driver's seat.
Sprayed the whole lot with waxoyl, works a treat and took about 10 minutes.

Excellent description - thanks dbo! Looks like ours is now working and we can stop checking if we've done our target of 430km

No need for any drilling to fix from underneath, the holes are already there

This seam has holes pre-drilled into it. Now look towards the rear of the Bongo - Just in front of the (drivers side) rear wheel there’s a ‘T’ shaped metal plate that runs from the sill to the chassis. There are 2 holes pre-drilled in this plate. Select a hole on the tank, and a hole on the plate. Measure the distance between these holes. Cut a length of electrical wire to this length. Attach a connector to each end of the wire. Use nuts and bolts to attach the connectors to the holes

Theres always more than one way to skin a cat,what difference does it make as long as a FIX is the end result!

Totally agree that's why I was explaining to peeps that you CAN do it from underneath easily without drilling anything (as we've been saying for a while), not trying to upstage anyone or have a pop, just trying to help those that may not be able to easily access the top of the fuel tank (if they've got a floor/conversion etc) & think they have to start drilling holes in the fuel tank or anywhere else

.
It can also be done by dropping the fuel tank if you really want to, but unless the sender is fubar, there shouldn't be any need.

At the time of my original post I didn't know it could be done without drilling, Would an admin edit my original post to state this, so not to confuse peeps or put them off from fixing the faulty fuel gauge from under the bongo, rather than the fix I suggested, as its been said before as long as it works that ok.

That seems ok to me, if anyone else has any suggestions (polite ones please

) then pm westonwarrior and he can edit or add as he thinks fit.

If you don't mind me saying so guys, it could be a gauge issue in some cases with earth continuity from the tank to the chassis as opposed to the earth just from the sender to the tank...?
My guess looking at how the tank is slung under the van...
http://lushprojects.com/bongopartsmk2/c ... mgno=.html & bearing in mind tainted/dirty/waxoiled tank bolts & brackets??

A simple classic example of of earthing the tank to the chassis!
I did mine like this...
& it works for me!
However, its worth mentioning if after doing this you find it don't...? (& i'm not suggesting it wont.)

Try running an earth strap from Dave's pics to where Briwy mentioned... There are earth points under the drivers seat on the chassis near the air filter....

Good point jaylee

I suppose it could be done all in one go, one wire from the sender and one from the chassis both connected to the earth, a bit of a belt and braces fix.
