remove fuel gauge sender
I am helping a friend with a 66 Lemans. Can the fuel level sending unit be removed with the fuel tank still in the car? The 66 manual doesn't say.Thanks in advance Andy

Yes and no. If it is the same as my '67 GTO then it will be very hard, even on a lift. Here are 2 photos. The first shows the old unit in the tank with the tank in place. The crap all over it was gas tank stop leak. As you can see, you can get the fuel lines off along with the wire to the gauge. That's the easy part. To get the sending unit out you need to rotate it counterclockwise (I think). There are 3 tines that lock under 3 tabs. There is a tool but I've never seen one. Tapping on the tines will probably loosen it. All relatively easy. Putting it back in, well.....
The second photo is the new sending unit I installed in the new stainless tank. Hard to see but there are vertical stops on the tines that hit the tabs. That's what the tool would lock on. There is a big O ring under it that seals it all up. It took me and my brother 20 mins to get the tines under the tabs without destroying the whole shebang. And that's with the tank out. In the next answer box I ll post a link to the whole album. Take the tank out if you can.

I posted some pics along with my opinion about success. Because there were links that would show the photos, a moderator needs to approve them, which is understandable. Anyway you can look in the album while we wait.

I'm thinking that for 16.00, I'm going to buy the tool. If our host doesn't carry it, then I know where to get one. I'll be doing this same task first thing when the car comes out this year.

Never used any tool - good idea but never bothered. If you are not using the tool, a blunt, non-sparking drift will keep things safer - a brass drift works good. Worse tool would be a screwdriver since it will dig into the relatively soft ring tangs. Helps a lot to grease up the O-ring so it will self-center as you push everything in place. Tank should be drained down as far as you can get it. I usually end up going back in and tweaking the float rod so that my tank reads empty when it has about two gallons left in it. Sounds easy, but not unusual until you play with it to either run out of gas with it still showing fuel, or showing empty and the fill-up only requires about 3/4 of what the tank holds.

I replaced mine with the tank in the car. As above I drained as much fuel out as I could. Didn't use a special tool, I didn't know there was one. When I got the sender out, I didn't have any fuel spills which was nice. It took longer than I thought to get the new sender back in, but every job I do it seems always takes longer than I thought it would. Just Take your time, you shouldn't have any problems.
