I bought the "BD-Power Dodge Lift Pump Kit (Auxiliary)" from xtremediesel #BD1050226 and started installing it last night. The pump is activated by a oil pressure switch which is installed into a oil port in the side of the block (just under and behind the injection pump). Anyways you remove this plug using a 5mm allen and install the supplied 'O-ring to NPT' adapter fitting and then the pressure switch into the NPT side of the fitting. Anyways this O-ring adapter comes with an o-ring and a seperate thin steel washer. But in the install direction it says:

I read that as I'm suppose to use the supplied composite rubber/metal washer which looks like a fuel line washer for a banjo fitting on the o-ring adapter.

So my question is do you:

a) remove the o-ring/washer and just use the composite rubber/metal washer on the adapter or

b) are you suppose to double stack them and use both??

 

i coundnt see why it would hurt to double stak i have the same system but cant remember how i did it.it was a long time ago,1999. give bd a call a see what they say.Plant Headquarters
