Hello BenzDiesel
I suggested the use of channel locks because not everyone is strong.
One of my friends owns three diesel MB and has Multiple sclerosis.
RE: Whunter mentioned trapped air and the auxiliary fuel pump could possibly be the culprit. But then H202 had a spare pump and confirmed that channel locks were not needed to depress the auxiliary fuel pump's plunger mechanism.


OK whunter,

About the pump, it takes some pressure to depress the plunger, but most mechanics, if not all of them, should be able to depress a plunger on that particular pump with ease and I still have that as the potential culprit. If the mechanic can't handle that pump there is no way he is going to be tossing a 603 cracked head around. As always, I'm thankful for any information that even has a chance to be beneficial in solving my fuel issues.
