I bought 3 Sierra Water Separating Fuel Filter, Long - 18-7945, and installed them on my boat... My engines would not run... These filters do not work on my 7.4 MPI (L29) Mercruiser Engines... I had to reinstall my old quicksilver filters... and yes, I did prime the filter with fuel prior to installing them... I wasted time and money... I will now stick with OEM or Quicksilver.
