What is the best way to treat or repair Sugar in Fuel tank? The van is running fine but I saw the sugar in the fuel filler neck while pumping gas?

Hmmmmmm. Sugar in the gas tank? Do you think maybe somebody hates your guts?

Here is how you drop the fuel tank of your Astro. I have done this more times than I want to remember.

By the way, I bought a replacement gas tank for a 91 S10 and found 3 pounds of sugar in it.

It is not that bad. I have done this damn job so many times that I can do it blindfolded in 45 minutes.

When you get the tank out, fill it and rince it with water and drain it several times and then roll up paper towels in a tube shape and sop out the rest of the water until bone dry.

OK, let's pull the fuel tank. You HAVE to drop the tank just 4 inches and dissconnect the lines or you will break the plastic neck connections on the fuel pump and ruin it. This is a $300 mistake.

Jack up the back end of the vehicle on both sides and support it with jack stands on the outer ends of the axles leaving just enough room for the jack between the stands and the wheel.

Unplug the electrical connector on the front of the frame in front of the fuel tank. Get 2 8x8x16inch concrete blocks and put one under each end of the fuel tank. Undo the strap bolts both front and back on the car outside body side only. This lets the fuel tank down onto the blocks. Next to the driveshaft, undo all 3 hose connections. Undo the hoseclamp on the filler hose right at the fuel tank. Bend it and fold it out of there. Using the jack again, raise up the rear end of the tank, remove the block, and let it down to the ground. Doing the same on the front end, get the block out and let it down. Drag the fuel tank out from under the vehicle.

Was this
