It took about three years, but our home-brewed biodiesel finally broke down the return lines on my 6.2L. What's funny is that they all started seeping at the same time. They looked like those soaker hoses you put in your garden...they were oozing fuel all over the place. I ordered some Viton hose from Greaseworks.org and replaced all the lines last night. All my larger fuel lines still seem to be in good shape.

I also noticed last night how little I drive the '81 anymore. I've averaged 2500 miles per year for the last two years. Since my wife bought a minivan, I've been driving the Tahoe. But the '81 is still fun to drive! Lots of power...runs circles around the 6.5L.
