where is it spewing oil from?the HPOP itself rarely leaks.before pulling it off check the lines and fittings to be sure they arent the leak.if its the rear cover of the hpop leaking youll have to wait till somebody that knows how to replace the seal to come along or just replace the HPOP with a newer super duty pump with the humped rear cover.
removeing the HPOP is easy.
remove theplug in the top of the HPOP resevoir and suck the oil out .remove the fuel filter canister.there are to 13MM bolts that hold it on in the back of it on the bottom.remove the fuel line from the rear and fuel pressure regulator.on the front of the engine under the HPOP resevoir you will see a cover with 2 13mm bolts that hold it on,remove this cover.you mayalso need to remove the exhaust back pressure sensor from that little cover.but you might be able to bend the tube enough to get a socket in there.now remove the 18MM bolt inside the timing cover behind the little cover.remove the HPO lines from the HPOP.unplug the IPR.there are 2 10MM bolts that bolt the pump to the cover.remove those 2 bolts and pull the pump off.
