TC Fuel Sending Unit

Post by TBrad » Thu Jul 12, 2018 7:47 am

Inside the fuel sending unit, there appears to be a fixed capacitor and two movable blades, one on each side, connected to the external float. As the float moves down and the blades rise the right blade comes in contact with another fixed blade at the top, which is connected to the electrical contact wired to the low fuel light on the dash.

My question is; does the movable blade go on the inside or the outside of the fixed blade? My hunch is it is supposed to be on the outside, away from the capacitor.

An often misunderstood thing. No capacitor or resistor inside.

It's a simple on/off switch. As the float drops the arm fixed to the float lever touches the contact fixed to the body and earths the warning light which is live at all times.

Fuel Sending Unit coming up, maybe next year.
Checked your site out, you have inspired me. I fell in love with TC @17, bought in 1963 in Philadelphia, PA, got it running in Kansas, drove to Long Beach, CA, parked it in 1966, now just starting to pull it apart again. Looks very much like yours after sitting for 52 years.
I need to set up a site to illustrate the story like you have done.
Well done, Lynn & Norman!

Hi rwag66. Will look out for your site with interest. Just had TC4904 with XPAG5567 delivered to the shipping agent in New York for onward journey to my home in Cornwall UK. It`s been sitting unused since 1956 and a one owner car. Excited is not the word for it.

Rwag, I started the daily blog to record the rebuild of TC10178. When the car was finished I posted thet the car was finished so I would stop the blog. I got nearly 100 emails asking me not to stop so it carries on to this day.

I keep mine simple and use Pagebreeze html editor. You'll need a some web space to store your blog and you can get this from many places.
