Is the fuel pump in my tank also?
285,000 miles. Should it be changed out?
Are there other "things" I should be aware of, failing due to age?
I recall the Army maintenance unites had a sign which read:
The 5 Army "P's"
"Preventive maintenance Prevents Piss Poor Performance".

Along the line of preventive maintenance consider replacing the two high pressure oil lines that go to the fuel rails on the cylinder heads. The Injectors use very high oil pressure to open, when the line blows your left dead in the water and have a completely oil soaked underside of your van. Had it happen to me on my previous 7.3 van, luckily it went when the van was parked in front of my house, but the week before was out running around Death Valley with the family on a solo trip. Would not have been good if it went out then, got very lucky.
