FL WTB Fuel Sending Unit - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**maverickmk** · 05-14-2021, 08:40 AM

I have purchased 2 fuel sending units from 2 different vendors and both of the floats are filling up with fuel. Does anyone have sending unit for the in-cab tank with at least a good float? If all else fails I may try to pull the one I have and see if I can get it to dry out and then use that spray flex seal stuff

*Edit: I have an I6 - 250*

I have a good working fuel sending unit pulled from a '70 3/4 ton with 350 V8. Not sure it has the float with it tho. Will check the parts stash later today and get back with you.

Thanks, I appreciate it.

Not sure if it matters, but I have an I6 - 250.

Had same issue couple years ago, and apparently this is very common. I ended up finding a plastic (not sure of material) float on ebay which snap right in, and still working. Seems like it was only about $5 or so. Just another option for those who might see this and having same issue. If I recall it was being sold for a Jeep of some sort that used similar float

edit: I believe this is the item

I'm using that plastic one too. It's working great!

Didn't find the sending unit from the '70 3/4 ton with the 350 V8. I do have a sending unit from a 67 GMC with a non-running in-line six. It looks good, moves freely on the float arm, still has the brass float and sock altho it is discolored with age.

Is there any way to test a sending unit out of the stock tank laying on the work bench?

Never have tried doing that before, no idea how. I do have a multi-meter but not sure how to attach the leads for a correct reading.
