Fuel Level Sender?
 
Hey guys, I purchased a fuel cell from summit a few years ago, and the fuel cell itself is great, but the fuel level sender has given me nothing but trouble. It's the type where there's a hollow tube that has a foam piece on the inside that's suppossed to float on top of the fuel to determine the fuel level. Anyways, it fell apart after a short amount of time, and even when it did work, it gave a very inaccurate reading. I felt up under it one time, and it was actually floating a couple inches below the top of the fuel level. So....

has anyone used this fuel sender before and had good luck?

It looks like a much better design than the one that came with my fuel cell. Any thoughts would be appreciated!

I have an Autometer version that is very similar. It gets caught up all the time and doesn't work very well. The issue is mainly due to the floating ball attached to a pivoting potentiometer. The arm has to move in an arc and it winds up hitting the interal baffling in my case.

In my Fuel Safe fuel cell, I use their SU012 Electronic sender. No floats to get hung up on foam.

It is composed of two concentric metal tubes; it has an potted, sealed electronics box on top about the size of a hockey puck, that bolts on top of the fuel cell plate. The concentric metal tubes can be cut to length desired to match the depth of your cell. No moving parts; the theory of operation is that the gasoline between the two tubes changes the capacitance between the two tubes. Easy to set up; cut the length to match the depth of your cell and install. There are two trim potentiometers on top. One is marked zero and the other is marked full. With no gas in the fuel cell, adjust the zero pot until your gas gauge reades Empty. Next, fill your fuel cell full of gas. Now adjust the full pot until your fuel gauge reads full.

My FuelSafe cell and sender have been in since 1996, and both have been 100% reliable.

Ditto on the Fuel Safe sender. Works great.
