1974 Grabber fuel tank sending unit.

As the title shows I need to replace my 74's fuel tank sending unit. It's a 302 car. I bought one on fleabay and surprise surprise, the chinese copy wont work, it's completely wrong (despite it saying for 71-75). That said no auto parts stores locally carry it. So some research I found this one from classic industries. The pic looks spot on.

The mechanic who has the unit and car said he thought the part number says D1DF9275AB. which doesn't match what I've seen online and he could be wrong. That said has anyone bought from classic for their Mavericks and all good? Any other opinions on where to get one?

 

Classic has provided good parts when I have bought from them. I replaced the tank and sending unit in our '70 last winter. I purchased those pieces from eClassics. Really nice parts priced well. Here's a link to their '71-'75 sending unit. Good photos there so you can verify if it looks correct.

Maybe I'll give that a try. It sure looks like mine. It's cheaper than classic industries too.

 

Their shipping is super cheap also. I've bought several things from them and have been really happy with the parts and service.

 

I hot mine from Melvins...

Thanks for the link. I did try Eclassics first. If that doesn't work I have another to try.

 

ACP or All Classic Parts is the main supplier, or only supplier of the stainless steel Maverick / Comet fuel sending units.
FK-EF036A - or D1DZ-9275-A for the 1971-75 cars.
FK-EF037 - or D6DZ-9275-A for the 1976-77 cars.

 

The one I linked for him in the above post is the ACP sending unit. Everything I have by ACP has been of great quality.

 

Mine causes the fuel gauge to read Full until about 5 gallons is consumed. I really don't like that...

 

Add a "in-line" resistor at sending unit output at tank.

Will take a bit of trial & error, I'd start with 5 ohm & work up or down as necessary. Basically, a value that just reaches slightly past FULL should be fine. I'm assuming at this point when tank is full, gauge sweeps quickly past full mark?

 

I did that with my 67 mustang, and for it to work right it had to be done behind the gauge. Not sure if the Maverick is the same way but what a pain in the meecrab! The gauge would go out of sight when full, then when it hit 1/4 tank the car would stall out with no gas.

 

Yeah, when I fill the tank full, the needle is pegged past "F".
My original sending unit didn't read "Full" until 5 gallons were consumed, however it was completely empty BEFORE the needle touched the "E" mark. I've lost count of how many times I ran outta gas in that car (and ONLY that car). Is the gauge the problem? Or the sending unit?...

 

Eceptin' maybe Lincoln, AFAIK all Fords are 10 ohm full and 71 empty. In cases that readings are "HIGH", resistor can be added at either end and have same effect.

My Comet has a Mustang fuel tank and readings are fine.

 

I had a '67 Falcon that gauge acted same, I used ¼ mark as empty. In five years of daily driving to work, I ran it out of gas once. That time I was about a mile from station... It bucked and chugged the distance, quit just as I pulled onto station lot, coasted to pump. Coworker that was with me said, "I never get that lucky". When we'd arrived at work that morning, I had told him we gotta get gas before heading home. Yeah, I forgot.

In the '71 Shop Manual, Ford says 8-12 ohm full & 60-86 empty. Meaning by this era few gauges are truly accurate. Take both full and empty readings, BUT the 5 ohm resistor should lower reading, may need 10. As I said it's probably going to be trial and error. If readings fall within spec, problem is likely with gauge circuit. Still, resistor should help. If float arm is bent downward, will skew readings to high side.
