    Default Commander 950 fuel pump

    I am using a stock jeep in tank fuel pump off of a 1995 wrangler. Im not sure if this pump is enough for the commander 950 multi point. I know this set up used a holley in line fuel pump at one time but im not sure which part number. Im being told the jeep pump isnt enough under wide open throttle. Any suggestions?

    Need more information.
    How many psi does this OEM fuel pump operate at?
    Is this for the stock Jeep engine & injectors in the vehicle?
    For reference, this is the external Walbro 255 LPH fuel pump used in Holley's EFI systems: http://www.holley.com/12-920.asp

    This pump came from a 91 to 95 jeep wrangler HO. It is supposed maintain from 40 to 65 psi. I was told these pumps have been tested at as high as 80psi but i cant confirm that. I know the supply line is 3/8" and the return is 1/4"

    Engine modifications aside, that pump will work fine with the Commander 950 EFI system.
