OZM29C Posted April 27, 2021 Share Posted April 27, 2021 Have you ever wondered what was inside a fuel tank sender unit. I have recently had to refurbish my fuel tank send unit so I took a few happy snaps to share. The soft solder that secured the fuel pick up pipe to where it goes through the sender unit had sheered. This in turn created an external fuel leak by the fuel sloshing around in the tank. I tried to re solder the joint in situ but met with no success. I decided to dismantle the sender unit so I could silver solder all of the joints proper. I am now just waiting on some rubberised cork gasket material in order to reassemble the unit. The sender units are well made but very delicate to get the internals apart. 1 Quote Link to comment Share on other sites More sharing options...
M29 Posted April 29, 2021 Share Posted April 29, 2021 (edited) Hi Everyone My T15 fuel sender was really bad. The ribbon inside just fell apart. So what I did was contacted Tri Star Radiator in NY and talked to Dan the owner who told me to send me the old sender and gauge I wanted to use and he would make me a new modern one calibrated to the gauge and tank size. I am including a couple pictures. Cost was around 225.00 USD. Essentially the top housing was all that was used of the old sender. I thought this was a great solution I could not find an original sender anywhere. So although not exactly original it is close enough. Hope this helps anyone facing a similar problem.

Guido Ferluga Posted April 30, 2021 Share Posted April 30, 2021 Hello I found the float on the tank of the generator is practically identical I just have to make the hole for the fuel fishing. I ask you if you can kindly give me the dimensions of the system for simplicity I am attaching a photo with highlighted the measures I need thanks Quote Link to comment Share on other sites More sharing options...
Guido Ferluga Posted April 30, 2021 Share Posted April 30, 2021 Just to understand this is a universal 12 V sensor for gasoline tank for marine use adjustable cost from 25 to 30 € you have to calibrate it with the tool and make the hole of the fuel Quote Link to comment Share on other sites More sharing options...

OZM29C Posted May 1, 2021 Author Share Posted May 1, 2021 Took the weasel for a quick test run to check that the fuel sender did not leak. All good now. IMG_3891.MOV Quote Link to comment Share on other sites More sharing options...

OZM29C Posted May 16, 2021 Author Share Posted May 16, 2021 Finally got the opportunity today to take the weasel for a 2 mile run to test the fuel tank sender unit repairs. I am pleased to report no more fuel leaks. Quote Link to comment Share on other sites More sharing options...

Dan @M29Thanks for the BZ Dan 👍Actually the restoration took 22 years. Still got some small finishing jobs to do like fitting the Canvas seat and seat back covers when they arrive from the UK but its drivable now, not a garden ornament. @Patrick TiptonPatrick, any chance you could right my photo please? I still don't know why my I phone randomly inverts photos?????? 1 Quote Link to comment Share on other sites More sharing options...

OZM29C Posted May 16, 2021 Author Share Posted May 16, 2021 What I forgot to mention, in the picture the red wire was the power wire for the later model electric fuel pump. As my weasel has the mechanical fuel pump, I have re purposed this wire to be an earth wire from the fuel tank back to the fuel gauge.

Price USMC Posted June 29, 2021 Share Posted June 29, 2021 So speaking of the later model electric fuel pump, I often hear of members replacing this in tank model with a late 1970's Cadillac part. Does anyone have this part number? and does it require an modification in the replacement process? Quote Link to comment Share on other sites More sharing options...
