The easier way to access (at least the way I think it is), is to remove the engine cover and access from inside the vehicle. You may have to remove the turbo oil supply tube to get to it easier though.

Thanks by the way!

Does it sound like a switch problem? Some times at idle it drops to "0". When I give it fuel, it comes right back up. I realize its either on or off. If it goes to "0", how long until there is no oil in the top to feed the injectors? Never is it hard to start and runs great.

Can I get at it from the front, or take the engine cover off and get at it from inside the van?

Same as where it's located on an F-Series, adjacent to the oil pressure supply line to turbo on the oil cooler top cover.

Can you tell me where the oil pressure switch is on a 2005 E350 6.0 diesel please?
