I run a 22 in my car, in trunk-first gen Camaro. I made it such that about three inches, maybe a little more, are above the nominal trunk pan, the rest is underneath the car. I think it looks pretty cool too. You need to vent the tank out of the passenger area of the car, and also will need to run a full firewall to sperate the trunk from the interior in case the worst happens.



So, I was playing with mine again last night (sending unit). I definitely works without the 12v lead, but I can't get it to adjust to empty, the lowest it goes is about 1/4 tank or so. Ironic too, because the gauge hadn't been working, and it is a 22 gallon tank, I always kind of assumed I still had "enough" gas. I ran out last night, luckily in the shop though!

That's strange, Mark. I wonder why they even put the "12v+" terminal on the sender if it's not needed??? Weird.

I'm sure you have, but I have to ask; Have you made sure that your sender is the correct length for your tank (bladder)?

Oh, come on now, Matt. You know me, of COURSE I haven't! I expected the darned part to come from the supplier correct!

Kidding aside, I hadn't even considered that, but it would seem to me that if it were too short, the tank would read "empty" earlier rather than later (as is in my case). Honest though, the darned sender is the least of my problems, I realized that my wonderful $120 optima battery is dead?!?! I'll sort the sender out later, but for crystal clarification, it doesn't work at all with 12v connected (were you using the stock gauge in your applications, or a remote one???).
