Fuel Tank Senders again
Posted: Mon Aug 18, 2014 9:24 pm
Hi Guys.
I guess many of you have seen my previous posting asking about fuel tank senders. Well I finally bit the bullet and in stalled two new senders in my 74 Tri Cabin. I ordered Moeller senders along with new gauges from West. I had previously prepared the floor over each tank by cutting out a 16" square hatch over each tank. I was pretty nervous about the whole deal, and shut down all power, 110 v & the 12 v too. Opened up every window, door, & hatch for ventilation. I used a self contained fluorescent light & hand tools. The old senders were originally installed with Phillips head screws which I thought would be hard to remove, but, they came out surprisingly easy. It was just a matter of lifting out the old senders, and I then cleaned the old sealant off the tanks with a plastic scraper and used a brass wire brush to really make a clean surface. The Moeller senders went in and were a perfect fit matching up to the original tank screw holes. Moeller supplied stainless hex hd screws along with a fairly thick rubber gasket. The screws even had their own sealant under the heads, and when sealant starts to come out from under the head while tightening, you are done. Installed new gauges into dash, didnt use the old original wire but ran new wires to each gauge. Turned on keys and had working fuel gauges for first time. Now one of the main reasons for this post is that I would like to pass on that my fuel tank senders were not the 33 - 240 ohm type, but had stamped into the side 90 ohms. I dont know if these senders were Trojan originals, or had some previous owner replaced the originals ? Just thought I would pass on that my Ohm meter just gave me a reading of 80/90 ohms, which I thought was approx 1/2 a tank if they had of been the correct senders. What the heck, I guess I just kind of bumbled my way through it all. And that's one more job put to bed now. Take care guys.

Never even knew they used this type. Thanks for the info from you, and all of the rest of the guys who gave me advice over the past months.
