Richard got me thinking about it, and I said the low pressure pump is in the cannister, which is incorrect. It is located outside the cannister, and feeds the cannister with fuel, which had the main efi pumps sort of dangling from the top, which in turn feed the fuel rail. It is a fairly small unit, mounted close to the cannister. I have the old low pressure pump somewhere in my garage, that I think is good, as my trouble ended up being the relay. Email me if you have an interst in getting it cheap. amjbishop at yahoo dot com. My thought on my boat was to just replace the low pressure pump from Skidim, as it wasn't that expensive, and by the time you go to a dealer with a gauge and all, I figured I just had a new pump for my old boat. I also bought a filter in the cannister, after like 7 years. The guys I ski with hadn't done it either, so I didn't feel that bad. See the PCM GT40 engine manual at link below, about 300 pages in PDF format on PCM or SN website. It has all the specs and troubleshooting guide. It was very good info.  http://www.planetnautique.com/CorrectCraftManuals/GT-40%20Service%20Manual.pdf One other thing you can do is clean out the checkball valve sitting on top of the fuel tank. Mine was marked with red tape or something as there are a few, mainly for venting and return from the pump. If this is sticking, due to Stabil or whatever, fuel flow might be compromised initially. This is a long shot, but cheap one. Low Pressure Fuel Pump: http://i109.photobucket.com/albums/n73/ab38off/fuelpump.jpg
