    I've spent some time looking for an inexpensive replacement pump. Found this chart showing a few walbro pumps and current amp draw at different pressures...

    http://www.autoperformanceengineerin...l/fpspecs.html

    still too high but informative

    even better... http://walbrofuelpumps.com/fuel-pumps-pressure-charts

    If you take a look at the GSL395 pump near the bottom it seems to run only slightly more amperage and pressure...only problem is it doesn't have the 7/8" center inlet.

    Here is the Kawasaki Spec:

    If you do the math(I suck at math) you need 19 Gallons(72 liters per hour) per hour flow rate at 20 ~ 28 PSI for Polaris DFI. Now notice there is a typo in the conversion from Milliliters to US OZ in the Kawi manual.
    If you install a fuel pump with more flow let's say 150 ltr/hr (39.7 gal/hr) then you fuel pressure will increase way to much increasing current or Amps, then overheating the EMM.

    So we need a fuel pump with a maximum of 80 ltr/hr (21 gal/hr) at 20 ~ 28 PSI.
    Now this fuel pumps may work:
    F20000283 (a.k.a. FGB-1), 87 ltr/hr (23.0 gal/hr) at 300 kPa (43 psi) with 13.8V source draws 3.8 amps, notice the fuel pressure is 43 PSI. If the fuel pressure is reduce or regulated to let's say 24 PSI then the amps will go down substantially. So 3.8 amps divided by 43 PSI is equal to .0883 Amps for each PSI for this FP. So 22 PSI x .0883=1.9426 Amps, 24 PSI X .0883=2.11 amps

    The same thing could be done with this one too:
    F20000297(a.k.a FGB-10), 76 ltr/hr at 300 kPa w/ 13V source [drawing 4.4 amps max]
    Notice this is the closer we can get to the fuel flow required by the Fitch DFI.

    Now we can use a higher flow fuel pump but we need to reduce the pressure substantially and the fuel pressure regulator is fixed, so if we supply more fuel flow pressure will go up and the load of the pump will go up = more amps(current)= heat= EMM fried!!!

    So if you are smart like "ME", who fail Kindergarten for 10 years, then you will know you can't compress liquids(well you can but...). So a new external adjustable regulator will be needed.

    So far any one agree, disagree, opinions, etc...

    HFP-378 Fuel Pump Kit Replacement for Polaris Ficht - Replaces 2410129

    EDIT: Found it. This pump appears to have the least amount of draw among the aftermarket pumps, which MAY make it acceptable. YMMV.

    Have you had a chance to measure the current on them or just going by the seller's spec?

    Yeah, my (other) aftermarket pump is about the same when just connected to PS under no load and no FPR connected. The picture doesn't show the whole rig..

    The picture shows the pump making 25psi at 3.65A...(not trying to defend the product, just stating what I see...)

    @12.32 on PS (alternator V is typically above +13V) and without the FPR in the photo I get the similar result with my aftermarket pump.
    It would be good if somebody who has purchased and installed it to report the readings back
