It can be done. You might want to move a couple of vacuum hoses out of the way and remove the windshield-washer bottle to give you easier access. As I recall, you need a thin wrench (maybe 14mm?) to loosen the sender. I bought a bicycle wrench for this application.

Yes, you'll need a short thin wrench as mentioned. The size could be either 14mm or 17mm on the old and new sender. Bike wrenches work great, just break it in half.

Hmmm... ok, so you can actually access it from top side? I don’t have a Lyft anymore, and mechanic want crazy $$ to do it. So I was wondering if if can be done DIY style. Just wanted to hear from someone who has done it. So thanks god the Yip. And again, I can access it top side if you recall?
thanks!

Note: those wrenches are called "cone" wrenches. Their use has declined with sealed bearing and large axle hubs but most bike shops still carry them for old or cheap hubs. Still in demand for us folks that like vintage bikes. Same to cut a Park Tool wrench in two like 6alfas did, but OTOH it is the best...

Most bike shops should have them. Hopefully they're open during the CV deal. I bought mine from Performance when they still had retail outlets. Some of the cone wrenches will cover both 14mm and 17mm sizes which is a big plus.

Does anyone know the exact size wrench needed for that right side sending unit?
As previously noted, it will either be a 14mm or 17mm hex behind the sender. And the new one will probably be the other size... It usually does not take a lot of force to get it loosened. Once it moves about 1/2 turn you won't need the wrench - it'll come off the rest of the way by hand.

I've been able to get them off/on with a thin wrench. But if you can't locate a bicycle wrench (due to this lockdown) I'd suggest getting a piece of 1/8" thick steel (maybe even aluminum) and make yourself a short, thin wrench (just trace the shape onto the metal and cut off everything that doesn't look like a wrench).
