I need a fuel sending unit for my 69 Dart. Any recommendations where or what to buy.
Thanks.....
Thanks.....
Repro's suck.
They don't go to the bottom of the tank and the proportioning of the readings are off from original. So it will run out of gas with gas left. And it will show full and then rapidly go to empty.
694spd, Save the lock ring from your old sender. The new reproduction rings don't seal properly....

Read half way down page: http://www.heritech.org/cuda/fueldelv.html
Many years ago, I wrote Year One and suggested that they start selling A Body Fuel Sending Units with the 3/8" pickup (instead of the measely 5/16).
6 months later, they had them for sale. They also offer the 1/2" for all out race. :burnout:
You should never put a 5/16 pickup in your Mopar, even stock. You really need the 3/8, it will improve your performance substantially. But you must continue the 3/8 ALL THE WAY to the Carb. Yes, they offer 3/8 line to fit your A Body, too.

You guys are absolutely Correct about repro Fuel Sending Units...outside of Year One --- DONT BUY THEM!!! THE ARE ABSOLUTE CRAP. :twisted:
I bought one off Ebay for the 3/8 and it has been a Nightmare.
Had to do the Job ALL OVER AGAIN after purchasing the Year One 3/8 version.
$45 on ebay for stainless one w/ 3/8" outlet & 1/4" return. Bench test it first. I had to pop open the can and bend the wiper arm so it touched tighter. I had the dash out and tested both together on the table and added some resistors on the cluster to tweak the signal to give a perfect reading at each stop. My 65 Newport w/ 383 came w/ a 5/16"D fuel supply. Fuel just pours out the front of the tube, so I can't imagine it restricting the engine. But, 3/8" is better. Corvettes w/ LS engines use that.
I wrote a post on the whole cluster work & resistors to tweak the fuel level reading (search). Re sender tweaks, it is simple & obvious. Bend the tabs back on the cover to expose the resistor & wiper arm. Bend the wiper arm outward so it contacts tighter. The arm is stainless so should hold that tension for a long time. Of course use a multimeter to measure the output resistance signal as you sweep the arm (free w/ coupon at HF).Do you have a thread on how you modified the wiper arm? I wanna try this before I spring for a new and pricey fuel system.
The main problem I have with the new senders is that they read linear, the original senders where non linear. If you look at the fuel tank, you will see because of the spare tire inset in the tank , when the fuel level is halfway down the tank, you have actually more than half of the fuel left. Have not been able to find a non linear sender. Some one here could make a mint supplying just the non linear wiper assy.
