KenEvans Posted February 28, 2002 Share Posted February 28, 2002 I've purchased a Malpassi "adjustable" pressure regulator from Demon Tweeks. There's no paperwork at all so does anybody know what pressure these provide as they come out of the box? Could save me having to seek a pressure gauge, though I am expecting the recommendation will be to measure the pressure anyway. Thanks Ken Link to comment Share on other sites More sharing options...
oilyhands Posted February 28, 2002 Share Posted February 28, 2002 Whatever the documentation says I wouldnt trust the pressure setting 'as delivered'. The only reliable way is to use a fule pressure gauge. Oily Link to comment Share on other sites More sharing options...
KenEvans Posted February 28, 2002 Author Share Posted February 28, 2002 Thanks Oily, I thought as much. There are no "in" and "out" markings on the ports, can I assume that the top is the pressure side and the side port returns the fuel to the tank? It's made in Italy so anything could happen......

Swiss_Tony Posted February 28, 2002 Share Posted February 28, 2002 Ken I think it is the same as mine.(low pressure for carbs) My one is marked for in and out. If you are local I have got a fuel pressure gauge. I am in S,London/Surrey James Link to comment Share on other sites More sharing options...
EFA Posted February 28, 2002 Share Posted February 28, 2002 If you set it for 50psi on one car and install it on a different fuel system, you are unlikley to get 50psi on it again. These devices need calibrating before use (and re-calibrating every year or two in my experience.)
