Well, replaced the fuel filter and it was filthy. Replaced it last fall and it was filthy then too. I had already checked FPR at the same time. Holds a vacuum and there is no fuel smell on the vacuum line. So that is good. My FPR bolts area actually on top so it would be easy to replace instead of trying to get underneath like some I have seen. As I was getting real close to sniff the vacuum tube I noticed that the FPR says Bosch on it. Go figure! Probably replaced before I bought it 18 years ago. But I have never had any kind of work like that done on the truck. The plastic vacuum line looks like it could rub thru some day, so readjusted it. NOW, all I need are the 6 bolts that hold the bed on and I am ready. The bolts are on order, but also the two front ones are back ordered. May just get some regular bolts just to get me not he road and then replace them when the good ones come in...

It has been a week with the new fuel pumps/tanks. No leaks I am able to fill both tanks with no overflow or gas fumes. The one thing I noticed is that it "seems" the engine is peppier, more responsive and smoother in the acceleration. It could be the old fuel pumps were less than optimum and I did not know it; maybe they were operating at the low end of their range. Now they are operating at the higher end. Never had any codes indicating fuel pressure or injector issues. So, all is good to go.....

That's the typical perception by any owner after any significant repair or modification, whether the engine actually runs better (and it might be in your case) or not.There are no direct codes for those since there is no fuel pressure sensor; and the injectors aren't wired discretely, so the EEC can't monitor them independently. At best, you'd get rich or lean codes.
