mat in tn Posted March 26 Share Posted March 26 I might've confuse someone with the last sentence, lol. So it's not me who started the thread. I'm just in a similar situation like OP was 3 years ago but unfortunately for me rock out doesn't have that part anymore. I tried googling the part # with no luck. Ebay, LMC, RA don't have anything even similar to it. I'm located in Europe so I really need to be sure before ordering as the shipping usually costs more than the part itself and returning it is a real pain. try bronco graveyard also and possibly NPD Link to comment Share on other sites More sharing options...
Tony69 Posted March 26 Share Posted March 26 try bronco graveyard also and possibly NPD unfortunately non of them have it I was thinking maybe a different style one would fit but as mentioned earlier I kinda can't afford buying multiple units and then sending them back. I have one in the f150 but its a single line and two prong connector style. I wonder if I could somehow scavenge and modify it, running external pump to make it work. These tanks are such pain in the ass but its nice to have two... Link to comment Share on other sites More sharing options...

Glad I changed over to 96 tanks and units. Link to comment Share on other sites More sharing options...
Ifitaintbroke Posted April 8 Share Posted April 8 Alright folks, time for me to chip in. I spent a lot of time back in '20 looking for this exact same unit. I've come to the conclusion that they do not exist in the aftermarket and possibly never existed as a replacementpart from Ford. Here's why: in my catalog at work (this problem is actually how I landed my job at a parts store) the ONLY rear sending unit listed is for a plastic tank. Mine, as the OP's, is steel. 87 had a steel tank. The same tank. I could not find a 86 rear unit for a steel tank anywhere, so I tried one for an 87 as it is essentially the same tank. Here's the problem: in 87 Ford changed the ohm range in the gauge, and therefore the sender. My gauge would read backwards, as Jim's does with his 87 gauge and pre-87 sending units. Apparently, as Ford is apt to do, they used some 87 tanks in 86 trucks, and made a "custom" sending unit for them using essentially an 87 sender with an 86 reostat. This piece is a true unicorn. That's my theory anyway. To put it short: if you are looking for this unit, you are wasting your time. As for the unit listed on Ebay above, it very well could be the same one, making me wrong. It certainly looks like my old sender. My concern is, what is the ohm range? It's probably the 87 and up range. Could be wrong though! Link to comment Share on other sites More sharing options...

I will say it took awhile for one to pop up (I bought it not too long ago for a fraction of this current price) and was surprised to see another one show up so soon. So based on that I would definitely put them in the 'few and far between' category. If you want and can tell me what test you want me to do, happy to grab my multimeter and check the nos one I have.

All you do is hook up a multimeter set to ohms on the 2 terminals going to the sender. Should be easy to identify. Then, check resistance at the extreme ends of float travel. Should be ~73 ohms with float all the way down, and ~10 ohms with the float all the way up. Link to comment Share on other sites More sharing options...

Matches the pre-87: https://faq.speedhut.com/kb/fuel-level-gauge-faqs/what-are-some-typical-oem-fuel-level-sender-ohm-resistance-o-ranges So looks like just a not very common replacement part. While the price of the current ebay listing is a bit crazy, for someone wanting a drop in replacement, it's an option at least. Link to comment Share on other sites More sharing options...

If I'd found that 4 years ago, I'd have snatched it up, price be cursed. Link to comment Share on other sites More sharing options...
T_Auto Posted May 22 Share Posted May 22 I might've confuse someone with the last sentence, lol. So it's not me who started the thread. I'm just in a similar situation like OP was 3 years ago but unfortunately for me rock out doesn't have that part anymore. I tried googling the part # with no luck. Ebay, LMC, RA don't have anything even similar to it. I'm located in Europe so I really need to be sure before ordering as the shipping usually costs more than the part itself and returning it is a real pain. We recently fought this same problem at our automotive repair shop. After looking over the wiring schematics and seeing that the 7.5 and 5.0 fuel system was wired almost identical led me to look up what a rear fuel pump for an 86 Ford F250 with a 5.0 looked like. And it was the one we needed! The Carquest part number was HS3496087. Link to comment Share on other sites More sharing options...
