fuel sender

[mopower]

wondering who makes a good fuel sender ? last one i bought never did work

Are you talking about the sending unit that goes in the tank?  If so, I don't see how you could have one that didn't work, unless the filter or something in the pickup was clogged.  I bought a 3/8" off Ebay last year, and just got the cheapest one I could find, and have not had any problems with it.  What size do you need?  I have my original 1/4" on Ebay right now for $10 (just listed last night).  It worked fine, I just needed a 3/8" after my BB swap.

we checked it ,its got juice to the sender and its grounded no workee.. brand new gauges from auto insturments.. sending unit no workee .was running a 3/8 unit

I see.  I was think no fuel no workie.

someone on here told me advance auto parts stock them, I plan on putting one in later this winter. I think they said $ 60.00 or so from there.

Mine has never been right. goes to empty in no time and then it only takes 9 gallons to fill up.

Wally - you most likely have to "calibrate" the sender. So what I mean here is that your float level is too high with respect to the variable resistor position. To correct this take the unit out of the tank and bend the float arm (at a factory corner) as if you want the float to be lower in the tank. Don't bend too much, just a little at a time. What this does, of course, is that the float is still in the same position when the tank is full but the resistor position is further up towards the full position on the resistor. This means it will take longer to go down with fuel burn, so will mean more gas to fill for the same position on the fuel guage. Hope this helps.

Thanks!! Ive been wanting to do that forever but I havent found the time. Then I fill it up again....  that helps confirm my theory though...

in stock ready to go if you need, thanks

Im thinking the best sollution would be to put a known % of fuel in, say half a tank if you can fit it without it spilling from the hole. I beleive I have an 18gal tank. and then bend it until you read a perfect half tank on level ground.......

Wally, I think that some of the repops have the wrong ohm register winding that cause the fuel sending unit readings to be off. Or so I have read.

When you put the unit in you may have jammed it up so it dont move... ask me how i know.....

 That's what I did with a sender bought from Adeals automotive. Seems to be right on now.

[wally426ci]

It definitely moves....  but it drops too quick and never quite reads full...

Will the guage read full if you remove the sender, hold the float at full scale up and temporarily ground it so the guage works? And also have someone in the car to view the guage and run it through some scale positions and see what you get. If you get the full reading then I still suggest the bush style calibration - IE bend the arm. Granted this is still not the best method but brings most systems to a happy medium ....... and when did you ever see an accurate gas guage from these vintage of cars? In the past I just set the odometer once I knew the "gas mileage" and filled after 300 miles in my old 67 Sport Fury 383 Mag.
