Howdy!

Just got back from the stealership. Went in because the LBZ would not change gears and lost power when I stepped on the gas.

Turns out they said it was a clogged fuel filter?

This rather confuses me. Should there have been some kind of code thrown? The fuel filter sensor on the DIC said it had 61% left.

What gives!

We are going to see more and more of this. Adding lift pumps is going to be a common trend.

This is how you can tell instantly what the status of your fuel filter is:

what was the mileage, that is odd you must have had something in the tank!
About 11,600 on the odo. About 6k since the last filter change. I do alternate between #2 and B20, but I would not think that there was build up that fast.

Using Bio will clog your filter if you also run #2 often. Bio is a solvent and will clean everything up faster than the Dukes can say YEEHAWWW.

Run one or the other, but when you mix it, you will plug the filter everytime.

On my last LB7 I hacked open the filters and 8K miles seemed to be the number for the crap fuel I was buying. The filter would be 3/4 blacked out at this point. Now factor in the new finer filters..........
