I have a 2004 df200 and so far it is a great engine. My daughter (who lives 600miles from me) sent me a water pressure guage as a gift. The guage kit is for a DF150-175. The instructions show where to hook up on the inline 4 but where do I hookup on the V6. Is there an adapter I need (part number)? I don't have a Suzuki dealer near me, I'm spending the summer in a remote part of Canada.
