New style (spin on) Raycor (diesel) fuel filters
I'm installing a gauge as well, readable from the steering station. When
I owned the Yanmar, I chose to abide by what the manufacturer said rather than risk my warranty. I'm funny like that. New system is going to take into account all the good advise you and other have offered. I'm not going to get caught with a dead engine again. DOug ps. Get a bigger dog "RichH" wrote in message ... If a 0.000000000002 micrometer rated filter has enough surface area it will operate with LESS differential pressure than a small surface area filter with 3 METERS pore size. This is a vacuum pump ... meaning that it only has to deliver 15 psi motive pressure plus about 2-3 feet of static head. A small dog can **** harder than that. The service advisory simply admits that Yanmar has a WEAK pump!!!!!!! A pump that cant run against a 'dead-head'is cheap, ill designed, etc. A clogged filter will always place stress on the pump. A filter begins to become 'clogged' when approx 85% of its 'dirt capacity' is used, less than that the pressure drop is linear, after that it rapidly accelerates the rate of 'clogging' (becomes exponential) ..... thats why you NEED a gauge to monitor it. |
