40 Ford gas gauge problem
Hey fellows working on a 40 Ford someone has installed a new gas sending unit,sometimes it will work and sometimes it pegs the needle like it’s grounded,thought it was wire going to sender,but ran a new wire and it’s doing the same thing,voltage going into gauge is 6v and going to sender is 4.5 v,any you fellas had any problems like this?thanks

Re: 40 Ford gas gauge problem
Those replacement gauges can be all kinds of trouble.

Re: 40 Ford gas gauge problem
You can test the gauge side using small batteries of different voltages to see what it reads. A D cell battery (1.5 v) should get the gauge to read around 1/2 mark. Here are some past post if your interested.

Re: 40 Ford gas gauge problem
its strange that even without it hooked up it pegs the gauge sometimes and sometime it don't thats why I ran a new wire,thought it was broke and grounded out,when I was trouble shooting it I grounded wire and gauge did nothing,ran the new wire it worked then drove less than a mile and it peged gauge.
