it was pretty steep, not sure the exact degree of the slope, but it was significant.
got it out today with a friends enormous 4x4 army truck. Once it was on flatish ground it crawled out of the yard and onto the street. parked it in a gravel lot to work on it.
The fuel filter on top of the engine has proven to be a nightmare to remove, all the plastic tabs broke when we laid a screwdriver across them to torque it. tried tapping it loose with a blunt socket extension and mallet, more plastic tabs broke off. Currently its just the inner plastic threaded ring remaining in the housing, we were able to dismantle most of the cap and pry the filter out, but now were stumped how to get the remaining plastic out without damaging the housing and metal threads. What a pain in the ass! judging by the brittleness of the plastic and the paint on the cap which matches the valve covers, were thinking this might be the original fuel filter?!? With 128,xxx on the engine I sure hope not, but it is seriously fused to the housing. Ugggg
