ok here is another development, Yesterday on my 88 7.3 idi non-turbo , I replaced the new stock fuel filter and housing. I have previously removed the water separator on the firewall and replaced it with another with a marine version. The new fuel filter housing came off 89 and has the water separator on the bottom of the filter and heater built into the housing, anyway after replacing that filter since I did not now of its history it has enhanced the performance for a bit more power going up the big hill. I also bypassed the water separator that I recently bought, but that did not make any more difference.
