Guys-

Got a 74 Dart swinger. Needs the fuel sending unit in the tank replaced. If you've never dropped the tank and put a new unit in before, is it easy to do? What tools do you need? The new sending unit has a round plate that looks as though it would need to be welded to the tank. If that's the case, I probably couldn't do it myself (no welding tools).

Advice?

Thanks.

No welding required, no. The round plate is part of the sender; the sender is held into the tank by this flange, by means of a lock ring and gasket. You will need a new gasket, and if your replacement sender didn't come with a strainer, you'll want a new one of those, too. Instructions for R&R are in the FSM, but you probably don't have the special lockring spanner. In that case, you can use a hammer and brass drift punch to carefully remove and reinstall the lockring. Do not use a steel drift! (sparks).

It should not be necessary to drop the tank. Jack up the rear of the car, put jack stands under the "chassis", and let the rear axle hang. Make sure you have less then a 1/3 tank of gas, and don't use a incandesant drop light

I know, I know,
I have made my own sender wrenches and also used the knock it loose method..but the real wrench is only 4.95 and shipping from usatoolwarehouse on ebay, so I got one. It made the task really easy. It is a ford 4625 fuel tank sender unit wrench. I got mine 2 days after paying for it with paypal. I note tis in case you, as I, like tools and figure this might be one that if used twice is worth 4.95...

If you let the axle hang and remove the right rear wheel it is very quick and easy. Also working from the side rather than under the car, any fuel that drips does not end up in your face or running down your arm. I would avoid working under a car when fuel of any amount is in the open, it only takes one time for something to go wrong. You can do the whole job in half to one hour including putting the car on stands.

Sounds good, but my tank is more than 1/2 full. What's the best/easiest way to drain the tank so it doesn't spill out once I remove the lockring?

go for a ride...............

Remove the rubber line from the stock pump and attach it to an efi electric pump - will empty your tank in a few minutes at most. New ones are over $100 but a junkyard item shouldn't be too much. I have a used one sitting around....

I managed to replace mine without even jacking up the car (but I do have new 5-leaf springs, and I am not a big guy). Any way, I just siphoned out the gas, undid the lock ring with a screwdriver with the tip wrapped in a rag, and installed the new one. I tried a couple of hardware stores for the brass punch, couldn't find one. I had a fan running toward the car to better vent under it.

Are you sure it is the sender? (I thought my float was bad) After I went through the hassle and expense of changing mine, it turned out to be the voltage limiter that was the problem with the fuel gauge.

Yep it was the sender. It's working now, finally.

Curious, which sending unit did you use as a replacment?

got a new replacement unit that was defective. My mechanic cleaned the old sender and got it working. Still have a new unit on the way, but may just hold it until the old one gives out. Wish my mechanic had just fixed the old one before I went to the trouble of getting one new.

Any of you guys used this one?

I can make five mistakes while you think

If you mean, have any of us bought from this seller, yes, I have. I bought a 64 Dart fuel sending unit from him. I had no problems at all.

I got one of these

http://cgi.ebay.com/ebaymotors/NOS-1963 ... dZViewItem

and it works great for my 73 Swinger

but it looks like the other guy's are cheaper and have a brass float instead of plastic.

BTW, can anybody tell me how make a long link like the one I have into a short word like Fireball's "ebay jewel" two posts above?
