    Pressure relief system?

    Are two prv's too much for an rxp? I figured while I was down there I'd try two. Worst case I'll plug one off.
    The hose is 3/8" ID. Too much/little? I have 1/4" nipples and hose if so.
    Any cavitation seen with a prv setup? A few grains of sand will stop the prv from fully sealing against slight vacuum at a hard launch, so I'm expecting cavitation issues.
    If she ever starts I'll let you know how/if they work!

    that prv you built will not flow to much so IMO you should have no problems with it

    I bought the prv's off of Ebay last year, I didn't make them. The streets, nipples, tubing, clamps were bought at Lowes or Home Depot. Probably Lowes... I've had hell with Home Depot being out of the exact thing I'm looking for. lol
    Texas Tool had the bit and tap. The scary part was drilling into that plastic... all or nothin' after that.
    If they work I'll be extremely happy!

    Every boat is different, I run a p at 85mph with no signs of stuffing! The Px tend to stuff around those speeds, there is a few members here that can give you more details on this topic. If your boat stuff you will fill it hopefully not bad enough that you get thrown out of the ski, fills like the boat is breaking.
