When You Assume . . .

well, you know.

So the green 99 won't start, I figure it's another clogged fuel filter (which would be the third in 50 miles). So I leave it alone for a couple of weeks, and decide I need to drop the gas tank and get it professionally refinished.

That was my project for the weekend - drop the tank and take it in on Monday. I get in the car, and it turns over but won't catch for want of fuel. Same symptom. I clean out the trunk just in case I need to do anything from the top, which was kind of a chore since the trunk had become my de facto tool storage area.

While I'm back there I decide to check the fuel filter, and yes there's some rusty crap in it, but oddly there's no gas in the line leading up to the fuel filter. Hmmm. Odd. Maybe the rusty crap has blocked the intake in the tank.

So I get the rear end jacked up, get under there and take off the drain plug for the gas tank.

Nothing comes out.

For a second I wonder if the rusty crap has blocked the drain hole, too. Then I rap on the tank with my knuckles.

The tank is clearly empty. Bone dry.

So I go get some gas, put it in, and start the car. After the time needed to repressurize the fuel system, it fires right up. Drives around fine.

So why would I assume that the gas gauge on a 35-year-old car would be accurate, when I'm having fuel delivery issues?

FWIW the gas gauge reads 7/8ths full. Both before and after this exercise.

LOL.

My Z likes to play games with the gas gauge too.

Just keep an eye on the filter. Drop it if keeps getting narsty. Yeah!

Haahah! And you were wondering why the car was getting 96mpg, right?



On a more serious note, do you think the tank might have a leak?

No, I don't.

But it's full now. We'll find out soon enough if it has a leak.

Buying some gas is cheaper than a tank refinishing. A little cheaper.
