Where can I get a sending unit for a tank like on this t ? Something I can get welded on, and any info would help. Posted using the Full Custom H.A.M.B. App!
What you have to do, if your tank doesn't have it, is you have to cut a round plate out of about 1/8 inch or 3/16 thick aluminum plate in the exact shape as the round base of the sender you select. Buy the sender first, get one to match the ohms your gauge calls for, and then make an aluminum plate to match the base and bolt pattern of the sender. The plate you make will have a big enough hole in the middle to allow the sender to drop in, but still have room for the screws that go around the perimeter. Next, take it to someone who tig welds aluminum (unless you can do it yourself) and have them cut a round hole in the top of the tank just slightly smaller than the plate you made and then they can weld that onto the tank. The senders are generally universal in the sense you have to cut them and adjust the arm length to make it work with your tank depth. After you do that simply bolt the sender down using the rubber gasket they come with, and you are done. Here is the one on my Sons RPU. The sender will look like this, you have to shorten it up according to your tank depth. Here, I found a good picture of how the plate will look after welding it on. The sender simply screws down to this plate. Don
We used to make gas tanks for the early Scorpion helicopters. We used a bung just like what was shown and a SW sender and gauge.
On my 23 I ran without a sender for the 3 years I owned the car. I used a Speedway 11 gal tank and wanted the top of it clean with no sender. I only ran out of gas twice in all that time because I kept filling up the tank and I could see down in there. The two times I ran out was because I simply forgot to check for a while and all of a sudden it was like "Oh s*** !" Some people carry a stick to put down into the tank for readings, but a gauge does make it much nicer. Don
The t in the pic was my first hotrod and I just carried a fuel stick. But I traded it for an A coupe and I have an extra spun tank but it will be remote mounted in the trunk so I would like a gauge. Thanks to every one for sending me in the right direction.
Madmak95: Here's a suggestion for a round tank ...ISSPRO makes a tubular sending unit that eliminates the float-arm type thats subject to rapid fluctuations as the fuel sloshes.. My tank was made without baffles and at first the dash gauge looked like a fan blade.The s/units are a standard SAE pattern, so mount plates,gaskets are easy to find.. They make all size units for different tank depths..Take a look at their site.. http://isspro.mybigcommerce.com/fuel-level-senders/?sort=featured&page=2
For a customers roadster with a reall odd shapped tank I bought a in tank magnetic float switch from Aircraft Spruce. Fuel level would hold the float up and when the level came down to the emergency level the switch would flash a light on the dash (fuel bounce) so that would tell him to start lookin, Light on would tell him to stop an fuel up
