stuck temp sender

[quote="Jim Davis"]I need to disconnect the temperature gauge from the block. I got the brass collar unthreaded but the line is tight as can be. So is the bigger pipe bushing that screws into the block.

Anybody successfully remove these intact? (Happens to be on a D2 5U, but probably the same on other models.[/quote]

Jim
I successfully removed mine recently. That bigger pipe bushing Has a very coarse thread and Mine Came out easy. It is Still available new And is called an ADAPTER part number 5B1959.
IF you have time I would let the "line" or bulb soak with some kind of penetrant. I fitted a Murphy gauge to mine which screwed straight in to the Adapter so luckily it is a common thread.

Hi Jim, Sometimes those can really be a bearcat to get out without damage. Usually the junk one from NAPA that doesn't work comes right out, but the rare old sender hooked to a really cool gauge that still works is stuck.

If you've got room try to work a small strait pick in there to dig out any crud that has collected behind the nut. If you can get the sender to wiggle you might just keep working it out. you can also simply unscrew the adapter and turn the gauge with it so you don't twist off the sender tube. Then you can work at it from both ends.

Good luck

Thanks for the input.

Bruce, I will try to pick out some crud and see if I can get the bulb to wiggle. No chance, I fear, of getting the adapter out--unless I can get the line and bulb out of it and then get a box end wrench on it or a 6-point socket.

You're going to need a set of line wrenches anyway, go for it.

I read a post somewhere on the interwebs about fitting a new bulb and line to your old gauge face if the line was twisted off. Basically you pick up a new gauge from the shop, drop the bulb in ice water to suck all the ether back down into the bulb, cut the line, tin it with solder, slip the lines (one from the old gauge, one from the new bulb into a piece of sleeve a bit bigger, solder it all together then you're good to go. Sounds like lots of variables in there but they swear it works and the gauge reads fairly accurately. Could be worth a shot if the line is cut close to the bulb.

I have seen that website/page. It's a possibility. So is the line wrench, though I think this would be the only time I would ever use a 1-1/4" one.

Go buy a cheap CHINESE made 1&1/4" Wrench and modify it to suit this project. No sense in trying to source an expensive Line Wrench that big that may not fit into the space you are working in!
