    Manufacturer's Part Number:

    Moroso's Accumulator connects to the pressure side of an engine's oiling system. When the engine is running, oil pressure forces reserve oil into the accumulator & compresses the air ahead. If oil pressure should suddenly drop due to hard acceleration/braking or severe cornering, air pressure immediately sends oil to the main galleries. When danger passes & the pump is once again primed with oil, oil pressure forces oil back into the Accumulator to prepare for the next emergency. Moroso Accumulators can also manually pre-lube engines before start-up to prevent cold-start scuffing and premature bearing wear.

  • I want to use this on a VW oil cooler, to block oil from draining back into the oil pan via the engines oil output port, the cooler is mounted higher then the engines output port. What is the minimum pressure needed so that the valve opens and oil flows

    Asked by: grandpanystrom
    This check valve will flow with 5 psi or a little less.

    can i use it for fuel?

    Asked by: mrpontiacjr
    It may not seal completely with fuel, depending on the type. These will work - http://www.jegs.com/p/Russell/Russell-Fuel-Line-Check-Valves/2861391/10002/-1

    Would this valve be suitable for use on a return line with a moroso air/oil separator (eliminating the nozzle on the collector so there is a constant return to the oil pan)?

    Asked by: J M P
    You should have no problem using this valve on the return line.

    What pressures is this good for? (Open/flow pressure and back flow pressure)

    Asked by: J M P
    THis is made for standard oil pump pressures - less than 150 psi
