How can we answer what it is worth to you
to have a properly working fuel gauge?
I don't think whether there is an access panel is really the deciding factor here, dropping a tank isn't fun to do, but not terribly hard either if the vehicle functions so you don't even have to drain the tank & store much gas if at all, can just drive it till near empty.
Am I understanding correctly that you have a 2007 CR-V with 2.4L engine? The fuel pump and sender can be replaced separately (or else they wouldn't sell the pump separate, looks like it uses a standard hose and clamps setup), but that doesn't necessarily mean you can buy the sender separately. Is that a big deal? I mean with 217K mi. on it, it makes sense to go ahead and replace the pump while you're replacing the sending unit, as long as you don't get a low quality generic pump with a short lifespan.
I was going to link to a Delphi $221 sending unit w/pump on Rock Auto, but in this rare case, autozone has it for the same price which can be handy should you ever need to take advantage of the lifetime warranty:https://www.autozone.com/external-engine/fuel-pump/delphi-gasoline-fuel-pump-dfg0923/556198_0
... at least I assumed this is the right part #, as it is what Rock Auto shows for your model year.
