Anybody ever say the hell with broken original gas gage, and just buy an aftermarket fuel gage? If so, where/what did u buy, and do you have to change sender also?
Thanks!
 
Usually nothing wrong with the gauge, it's the new repop senders that everyone is fighting as the rheostat isn't wrapped correctly.

So buy another sender? Any one sell a GOOD one?
 
Like Hen's teeth to find. Easy to verify your gauge works, just ground the sender wire to see it sweep, or better yet put a 10 ohm resister between the wire and ground and it should say full.
 
Make sure to check your float. When my gauge began to mark empty for no reason, I later found the float had filled with fuel, making it ineffective as a float thereafter.

I grounded sender from where wire attaches to it to body, fuel gage went to full....unhook ground, gage goes empty...should b about 1/2 tank presently....replaced voltage limiter too

I assume u would have to empty tank and remove sender unit to check that?
 
So there is nothing wrong with your gauge. Are you grounding the sender wire back at the tank.. or at the instrument panel. If panel, do it at the tank end to make sure you don't just have a wire issue. If your gauges work, your voltage limiter is fine and didn't need replacing.
 
Yes, unfortunately I had to extract a lot of fuel first, than pull the sending unit. At least we didn't have to drop the fuel tank ('72 Bbody).

I clipped a wire to the terminal on the sender.....(original wire left on), and ran to fresh body ground on frame....
 
Okay good, now make sure you have a zero ohm ground path from the tanks SENDER HOUSING to the frame. There's a bonding "clip" about 6" long that should go from the sender fuel outlet to the fuel line (to cross the rubber joint). Sender gets it's ground from the fuel line being clamped to the frame. Quick check use that same ground point you just used and jumper to the SENDER face plate... see if your gauge now shows 1/2 tank or what ever fuel you have in it.

Will do! Unfortunately will be tomorrow nite, but stay tuned and thanks again!
 
The sender can be removed w/o removing the tank.....just make sure your fuel level is below the sender opening.......

I have yet to have or hear of a new sender working properly out of the box and installed....

If i did decide to buy a new sender, is there one out there preffered?
 
I've been contemplating getting one from Bill Rolik, have heard his were spot on. My brand new el cheapo one has been nothing but trouble. Shitty reading from day 1 ....
 
Not to jack this thread but the gauge on my ‘69 RR shows way past full. Gauge comes up when you turn the key on and down when the key is off. It seems to just read excessively high. They gent who I bought the car from has said that it works just goes way out passed full when the tank is full. Says it’s close to empty at between 3/4 and full. Any of you have this problem?
