Most of the owners are using the P-240KC for replacement. I had trouble with the hose feeding the fuel rails blowing off ,because of wrong size hose clamps being used. At that time 2 years ago i did not replace the pumps as fuel showed around 52 lbs at start up then drop to 48 lbs at idle. I have an electric fuel
pressure gauge mounted on my dash along with tach and air/fuel gauge. Pryor to code 55 i saw fuel pressure drop to 42 lbs it didn't dawn on me until i made my first DYNO run check engine light came on. stopped the test and brought i home. Put TECH-1A on at home ,checked codes only code 55 showed.So did the test for amp draw it showed 6.45 amp for both pumps. New pumps will arrive Tuesday afternoon and the work goes on.
