    Jerry Hoffman – Tell me how you can fix this problem by adding another check valve, where would you install that? A properly installed fuel system has the pump go directly to the fuel rail, and the rail then goes to the FPR, and it bleeds excess fuel to the tank return. This is the way it is done so the excess fuel can cool the injectors.
    So where would you install the check valve? If you block the flow to the FPR, you get full pump pressure, no regulation. Reverse it and the check valve does nothing, the pressure still bleeds down. Put it after the FPR, same thing. The bottom line is a FPR SHOULD NOT LEAK DOWN, THERE’S A GOOD REASON WHY OEMS ARE NOT ALLOWED TO DO THIS.
    I didn’t spend a bunch of money on a Kent Moore injector test set to not be able to use it, nor am I going to install a push button switch for the fuel pump power in my dash in order to get my engine to start, this is total BS.

  2. :

    There are check valves that can be installed for an OEM-like maintenance of fuel line pressure when the pump isn’t running. This is very common for high flow fuel pumps/regulators though. I know when I fire my race car, which uses a pump/regulator combo that doesn’t hold pressure when it’s not running, that I either do one of two things. I either flip the main switch on an instant before I hit start (so the 2 sec prime does it’s job just fine) or I turn it over knowing it’s going to have to sync the ECU before it builds pressure, and then fires, which means it turns over an extra revolution or two.

    I’ve used other performance pumps/regulators and they generally behave the same, though there surely are exceptions out there I suppose. As best as I can tell they just work differently than OEM pumps, because they are designed to.

What is the difference between the Aeromotive 13101 and 13109?

  • The 13101 has larger fuel line fittings than the 13109. Other than that and the color, there is no practical difference between the two. We generally recommend the 13109 if making 500 hp or less, and the 13101 for higher horsepower applications, but this is simply based on common fuel line size recommendations.
