Cal, My 454 died a few times last week as I was closing up my summer house in Nova Scotia.
I was not getting fuel up to the injectors which I cracked open and the hand pump didnt seem to be working. I’ll bet my in line screen to the pump is clogged. I have always experienced good pressure while using the hand pump. I had to leave it in the barn in non working condition as I had no more time to work on it. Any tips appreciated…Scott
