It's been a challenge working on the 4.9 engine in the E150 a very tight place to use your tools but with patient and a lot of rust penetrating oil, I was able to remove all the parts that was in the way, to be able to install the new fuel regulator and the intake/exhaust gasket. way before I got to this point the bolts to the alternator and the air pump was seas rusted in, had to to use a ply-bar and hammer then out and this took some time I almost quick the process of trying to install the intake manifold and the exhaust manifold gasket.
