Perry, we replaced the bad #1 injector with a Reliabuilt injector we (miraculously) found in stock. And then I replaced the bad #3 with one I rebuilt from parts. Both worked well. And the interesting thing is I found nothing obviously wrong with either of the removed ones except I saw a lot of debris when back flushing the injector inlet filters. I pulled the filter on the #3 injector and found lots of flaky debris that was way bigger than it should be, considering we have a fuel filter after the pump. I suspect a collapsed main filter or a total lack of main filter at some point in its life. So I think our main problem is plugged inlet filters. We need to check the filters in the other poorly-performing injectors.
We’re always a bit strapped for cash so just replacing injectors at around $300 a piece for the measly 5 miles a year we put on this tank is a hard option to sell!
