Access to fuel tank selector

[texk]

Is there an access panel under the seat to allow me to get to the tank selector valve or do I need to drop the auxiliary tank? Mine has the original Sport floor mat and I don't really want to start messing with it if there is no access.

No access panel. You have to drop the tank.

There isn't an access panel all from underneath

Thanks. That's what I figured.

If your valve is leaking, I believe you can replace the o-ring with the valve in place.

But, why not do this...
Replumb the system, and replace the valve with an electric solenoid. You can leave the original in place, so it looks original.
Mount the solenoid rear of the aux tank on the frame. That way the fuel lines from both tanks are almost the same length. It's also a good place for an electric pump if you ever decide to go that route.

The original was really placed in a lousy location. It was selected for access to the handle, rather than function or service.

I consider the electric valve installation to be my most important mod. It eliminates the confusion some have had by switching the gauge switch and not the valve. With this electric valve all you have to do is flip the gauge switch, and the valve switches too.

Also, there is no chance for the flooring to be soaked with gas again.

You don't have to drop the aux tank to get to the fuel selector switch . It's above the frame rail and forward of the tank.
Like Blubuckaroo I also installed the electric solenoid/fuel selector switch . I was hesitant about it and let the switch sit in my parts box for about 6 months before i actually installed it . After that though I'm glad i did . It makes changing tanks so much easier { i have less concern about someone who doesn't understand the two switch scenario } . I installed mine close to the original location - high and up out of the way .

OK, ya'll talked me into the electric switch. I hadn't even really considered it because I was thinking of putting it in the same location as the manual valve. Leaving the manual in place for looks and mounting electric valve on the frame is a win/win. Thanks, guys!

Good choice.
My main reason for installing one was during my ownership, I've replaced the manual valve twice and replaced the stem o-ring a couple times. The manual valve tends to leak fuel and fuel vapor into the car when the stem leaks.

I know that some are concerned about reliability of electric valves, but this one defaults back to the main tank position if it looses power.

An added bonus...
The electric solenoid valve costs less.

I ran that same looking switch on my boat for ten years without a problem (knock on wood). Question though - The TBP switch is 5/16, and I would swear that my fuel lines are 3/8 inch. Am I wrong?

bronco t, my '68 definitely has 5/16" lines.
