    Electric fuel gauges and sending units

    I have a super cub with four 18 gallon wing tanks, the outboard tanks have electric gauges. I am still researching the installation and was told the outboard tanks are out of a Pacer. Do Pacers have electric gauges? The outboard tanks look just like an inboard but have a place for the sending unit/float that attaches with five 10/32 screws. The gauges and sending unit are both made by AC but no part numbers on them. I need to find a source to buy 2 sending units and 2 gauges. Any ideas?

    A good place to start. http://www.stewartwarner.com/en-US/Products.aspx

    There have been several manufacturers which have used S-W instruments without any apparent "FAA" approval documentation. In fact it was common practice. Do not become obsessed with this issue. They were likely just considered to be "standard parts".

    Univair sells the electric gauges used in the Pacer and Tri-Pacer. Here is a good thread on troubleshooting the electric gauges.

    I know a guy who is building a modified Pacer, he switched from electric gauges to sigh gauges.
    He should still have the sending units and gauges.
    I'll ask him to check this thread & get ahold of you
    if he wants to sell them.

    I don't trust electric gauges. Neither did my airline; we always compared fuel upload with gauge indication. Even with the trusty cork, I dip my tanks before going anywhere with a calibrated wood stick.

    I have no gauge on my wing tank. I do use the cork to tell me if fuel transfer is working ok.

    The electric gauge has gone wonky on my right 12 gal aux tank. No biggie because I know how much is in it before flight by filling it, sticking it, or dead reckoning. Then I just run it to empty

    I'm installing an EDM930 in my 93 Cub, plan to use the electric senders and the JPI for fuel level. So I will have some gauges left over. Send me an email, supercub180@gmail.com.

    I don't trust electric gauges either, Have had this cub for 33 years and the outboard tank gauges have never worked. I always time my fuel burn, but I may be selling it and since the STC called for electric gauges on the installation I though I would get them working. I think I have found all my parts, thanks for the help

    I don't trust electric gauges, either. From experience.

    I have one Pacer gauge. PM if interested. Cheap.

    If I recall Gilbert Pierce posted on the short wing site about using new replacement gauges as used in the Helio Courier or something like that. I had them in my Pacer, hence the used one available. Its taking up space, if you want it. Piper had a switch to select the gage on L or R tank, and employed only one gauge.
