    1998 Pro 785 water routing

    I wanted to double check on changing the routing on my 98. I purchased a stock (red, unadjustable) jetworks valve from 785 Lugs. I wanted to make sure I did this correctly before I messed anything up.

    Since it is a 98, there is a t-fitting running off the water outlet line. The line that branches from the t-fitting goes to the 4 way splitter, which then goes to each of the stingers.

    Can I just splice in the jetworks valve before the splitter and have the same effect as Randy's water routing? Mine doesn't have a thermostat in it either.

    I did it exactly as Randy designed his schematic, and I suggest you do the same. I drilled and tapped the red water manifold on the end for the stinger circuit. Removed the inline restrictors feeding the stingers after the cross fitting, and also drilled and tapped the restrictor on the cross inlet. I used a brass johnny bolt (water closet bolt) to drill out to .090, and installed the jet works valve in the line feeding the cross fitting. I also installed an upsized ball valve inline for the stinger circuit to shut for towing for engine flood protection. See pic....

    Yes that way is fine
    The 98's shouldn't have restrictors in the lines before the pissers

    Okay, so I'll just cut the supply line to the 4-way splitter and put in the Jetworks valve. I'm wondering if I need to do something about the sizes going into it though?

    Yes just cut the line and put the jetworks valve in somewhere near the gas tank so you can put the valve under the gas tank strap.
    The only line that might have the wrong size orfice in it is the 1/2 hose going to the mag head pipe .I'll check it out for you .

    The 1/2 hose uses a bigger orfice in the manifold bar and head pipe so you might want to try and change it if you can get to it but i'm sure it won't make a huge difference in your preformance if you don't . I can check with Randy if you'd like .

    Are you saying keep the stinger circuit fed from the main water outlet line and not the distribution manifold? Was 98s restrictor at the cross .090? Or was that just a Randy tweek?

    There are restrictors between the stinger connection and the 4-way connection.

    I'm confused now what I should do!

    It seems like your setup is like the 97 like mine was. If it's like mine was it will have a restrictor at the cross fitting inlet too. Why they dbl restricted the stingers I couldn't make sense of.

    Anyhow, I don't think you can go wrong if you do it like Randy would.
