when my fuel gauge reads empty I still have half a tank left. I know I will have to remove the sending unit and rebend it. My question is where should I bend it and how much? Is there  way I can test so I do not have to do it a hundred times? thanks alot

COKE

I think i have read that  you should to put 10 gallons in the tank so it should to read 1/2 Tank.
This amount of fuel also allows to you to remove the sender so many times as you need without the trouble of fuel falling from the tank hole.

I just wondering if somebody does make a new sender wich does not need to be calibrated before to install it.

Just my  :Twocents: here, but my car acted the same as yours E on the gauge had 10 gallons in the tank and when the tank was full it only read 3/4 of a tank.
I bought a fuel tank package with a new tank, sending unit, straps etc... and when it was all said and done there was no significant change in my fuel gauge reading. I bent the rod, tried all kinds of different combination's and floats, bends etc.. the gauge is correct and goes to full when you ground the pin at the tank. I read somewhere on another thread that all of the new reproduction sending units have a different range of resistance than the original factory sender,  so none of them read right. I'm giving up until I can come up with a better solution or can confirm that a NOS sender will fix my problem. Hopefully someone out there has a solution!

I have a problem with my fuel gauge also not reading right  :shruggy: So I would also like more info on after market fuel senders, witch ones are good,or should I say work right. What brand fuel sending units are you guys using out there and who did you get them from :shruggy:  This is one of the problems I have on my car that I want to fix this spring, it would nice to know how much fuel is in the car.  I don't care how much it costs as long as it works right :2thumbs: Any info on this would be great :2thumbs:

All those re-pop sending units are ...what's the technical term.....crap. All have the same problem...reading 3/4 when full. Roger Gibson will have theirs coming out any day now. They are testing perfect.  ;D

I have 3 cars to fix now   :rotz:

Don't mean to sound dumb, but who is Roger Gibson :shruggy: Do you have a contact #.  There are so many people making stuff out there it's hard to keep track of who's who.

I've replaced several sending units within the last year and a half.  I check them before they're installed to see if the gauge will read Full with the float in the upward position.  So far, each one has worked the gauge properly.  As it was noted above, I try to have about 10 gallons in the gas tank.  This allows you to remove the sending unit without losing any gas.  I bend the float arm so the gauge reads 1/2 Full when the sending unit is installed.  I also make sure that the sending unit is well grounded.  I've had to run a ground wire from the sending unit to the frame in order to get a good ground on some cars.  One sending unit I purchased even had an extra terminal on it specifically for a ground wire.   I've had good luck with sending units I've purchased from Year One and The Paddock.

Not sure of the cost yet....Maybe I can get the site members a discount if they are interested. They should be arriving in a few weeks

edit - actually read from the beginning and answered my own questions. :brickwall:

vancamp

mine is reading empty  (still havent removed the electric pump) so i figured it was the ground I grounded the sending unit wire and the needle pegged out, tried grounding the line coming out of the sending unit to the frame and zilch :shruggy:

Mine reads low like that because i have a bad connection. Blue wire in the harness under the EBrake Pedal.  :Twocents:


Just need to get around to cleaning it...

Martian R/T

I got mine from Year One a few years back and it was in a Chrysler box, it had been reworked with the 3/8" tube, the part # on the box was for the 5/16" tube, it worked fine, but over the last couple of years it started reading off, when I took it out when I was having fuel problems earlier this year the cheapo plastic float had fuel inside it, so I bought a Ford brass float and fixed the problem. :2thumbs: :2thumbs: :2thumbs: :2thumbs:

Have you made the switch yet, and who is Frank Batelsen.  I just checked my fuel gauge problem today, I need a new sending unit.

I actually have made the switch, but I havent filled it with gas yet.

It does read a little higher after the switch than it did before. But the true test will be when its full of gas.

.......Stay tuned.
