The fuel pump you recommended uses hose clamps and the outlet side is
    short and can only accommodate one clamp, I'm going to see if I can
    find some with NPT or AN fittings. Incidently, That $100.00 pump looks
    exactly like the one in Summit Racing Catolog for $167.00.
    Didn't you get fuel flow readings when you had the 13B on the dyno? I
    need a ball park figure for when I flow my needle valve. Karibian

    It is 25 gallons an hour full power and 10 gallons an hour cruise.
    I don't see how that needle valve is going to give uniform flow in
    all those tubes. I can't see inside of it. Can you make a sketch?

    Karibian,

    Good to see you are forging ahead with the mechanical fuel
    injection. It looks like a low-pressure system with no return flow.     With six injectors you should get good fuel atomization, even with
    low pressure.

    If this works, it will provide others with a template for a simple     fuel solution with cockpit mixture adjustment.

    Btw, is this an RX8 engine? I thought two of the injectors on the
    RX8 were right on the housings?

Paul,

You asked me to remind you to dissect the one-way check valve on your
Walbro-type pump to see if it might need a secondary backup check valve.

Yes Scott. Thanks for reminding me. Unfortunately I am in LA today for a trip
to Mazdatrix so I will
be back tonight where the Walbro pump is. As I recall I did not see a one way
valve in the Walbro pump. But I will double check tonight.
