After a seemingly endless battle to get our 82 300TD to quit being the worlds most gutless vehicle, I'm wondering about the tank screen.

I've been really good about keeping the filters fresh, adjusting the valves, cleaning the banjo bolts, adjusting the throttle linkage, air filter, etc etc etc.

This week, I installed freshly professionally rebuilt injectors...

She still smokes bad at idle, and if I rev her much over 3k, she lays down a smoke screen - and she's still gutless across the board.

I ran biobor for a good 4 tanks worth, and noted little in the in-line filter in the way of debris.

SO: is it, or is it not, a good idea to use compressed air at the in-line filter, and blow back into the fuel tank? Seems I could at least test, even if only temporary, whether the screen 'may' be the problem by doing so, but if for some unknown to me reason this is a bad idea - speak up!

Thanks - Joe
