I bought a 1988 Club Wagon in January of 2003. It has two fuel tanks and a switch, that looks like it is factory-installed, for going from one tank to the other.
The weird thing is, the second time I filled up and kept track of miles to figure out what the mpg was, I never switched to the second tank; after going LOTS of miles, I finally switched and the other tank was almost empty. It was as though both tanks were supplying fuel the whole time.
It never happened again. For almost two years, I have had to switch from tank to tank, as I figure I would have to.
Then about a month ago, it stalled while using the front tank. I switched to the rear, and it kicked back into full force.
Since then I have found that it will eventually stall if using the front tank. So I only use the back one now. But this left me with about a half tank of gas in the front. I kept trying to use the front to empty it but the gauge hardly went down.
Then one day after I filled up the rear tank to be sure I had gas to switch to, I noticed that the front gauge had increased from about 3/8 to about 5/8.
huh?
Are these tanks interconnected? Do they both pump at the same time, regardless of the switch? Is the switch NOt switching and making both pumps work?
Anybody?
