New Fuel Tank - New Sender install issue.

[Tazio]

I'm recommissioning an 84/5 car, the original steel fuel tank was full of rust, and I do mean full, and wasn't worth saving, also the original fuel sender was seized solid. Consequently I have bought a new Caterham alloy fuel tank suitable for  carbs, and a new fuel sender, which is where the problem lays. 

The sender is used on differing tanks and as a consequence comes in two pieces, the sender including an integral arm, and is supplied with an additional arm with the float . Effectively you have to determine how long the float arm needs to be, which is effectively limited by the internal tank baffles, and the two arms are cut to appropriate lengths and fixed together, with what are describe as 3, C clips, which clamp the 2 arms together.  

My question is , has anyone had to do this and did the C clips work, or did you find a better method of fixing the ams together

Alan, I have the same set up and my sender did not come with any clips.  Although not my source I have found this on the Holden website: 

Top Mounting. Standard SMITHS fitting six holes 5.08 mm diameter on 60.33 mm pitch circle diameter. Gasket supplied. The arm length is adjustable for rectangular and cylindrical tanks of depths/diameters between 203 mm and 610 mm. After adjustment the arm is secured by soldering. Fitting and wiring instructions are provided. You will need to run a wire from the Sender to earth. For use with Smiths Classic Fuel Gauges. 12 volt. Resistance 20 to 220 ohms.

So they say solder.  I have yet to try so cannot say how easy it is to do

Andrew,

Thanks for that input, I think perhaps  a combination of the clips and soldering will give a more robust method of fixing, daft thing I'm at that age where even with glasses these little clips are a real challenge, lol.

I lockwired mine in place and soldered it.....

Remember to remove the float prior to soldering  , and put a heat sink toward the sender end too.

Cheers Neil, now just need to determine the length....

Alan, the Blue Peter way worked for me - make a cardboard copy of the tank to trial fit in

Did you use 'stickybackplastic' ?
