fuel gauge

[jsloan50]

I have a problem with the fuel gauge of my Marina based Roadster.
When it reads half full it is empty,can anyone help me sort?

Re: fuel gauge

It is a common problem with the Marina based Roadsters. I removed my sender unit and re-bent the float arm and it made it 90 per cent better.
If you do a search on the forum you will find other ideas what other owners have done.

Except when the 'floaty' thing comes off and 'floats' around the tank.
All better now though, fitted a new one last month.

Re: fuel gauge

Didn't someone graft a Marina sender onto an Escort flange. I can't find it in Pitstop but I am sure it was published. Along with a new electronic voltage regulator, it has to be the final solution.
Perhaps it has made the latest edition of Tech Tips.

Re: fuel gauge

I had this problem with 2 Roadsters & a Berli. I just carried a can of petrol and filled tank every 120 mls shown on mileage.

Re: fuel gauge

I fitted Triumph gauges and grafted a suitable Triumph fuel sender unit to the original Ford Escort pick up tube. Works well after I "calibrated" the unit [bent the pick up tube]

Re: fuel gauge

I used a 15 ohm resistor in the circuit between the gauge and sender unit. This brings the needle down to near empty before you run out of fuel.

Re: fuel gauge

I also used a resistor initially but have since adjusted the gauge using the two adjusters on the rear when I made my new tank so that it reads accurate at the bottom and fair at the top.
I have about a gallon in when the gauge is just entering the red and about 3mm off full when the tanks full.
It was very much a trial and error job as one adjusts the zero and one the amount of movement. Can't remember which was which 'though, but if you have a play it soon becomes obvious. It helps if you have a 10volt supply and the gauge and sender set up on the bench.
