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

Too much pressure/volume can damage the screen if you're not careful!
The best way to ascertain whether your performance issue is fuel tank/system related is to simply rig up a bottle/jug under the hood and feed and return fuel from that as you take the car on a real world drive around town. If the performance improves it's the tank screen/lines from the tank, if performance doesn't improve the issue is further down the fuel stream or something more mechanically oriented, timing, compression, IP failure, etc.
The TD is somewhat easier to access the screen as it can be seen and reached directly from below. If you need to you can drain or run down the tank (drain it as far as possible by disconnecting the feed line at the tank and direct what flows out into a bucket), pull the screen and then use gasoline to flush things out buy pouring and catching a bucket full through the tank a number of times. Just let the run out settle some between pours and don't re-pour the stuff/particles/slime etc that ends up in the bottom of the bucket!
On the TD you also have the advantage of pulling up the liner under the third row seats/compartment and pulling the fuel sender, with that dome you have a perfect view of what's inside the tank at the fuel pick-up screen area!
