I have a 1985 Hino WO4D ( 110 hp)
2 weeks ago, I took the boat out for a short trip down a river that my marina is on. No wake zone. I was doing 1100 rpm.
When I returned 40 minutes later I noticed the smell of diesel fuel. It was in my port side bilge and dripping of my motor Long story short, I found a fine spray coming from the end of the 2.5 inch rubber fuel line that connects to the injector rack on top of the motor. No split, you could see it coming out of the end of the hose. Since this short line was original (painted green along with the rest of the motor), with the same stock "spring" clamps, I just decided to replace the fuel line and use standard hose clamps. Bad mistake. I didn't know that standard fuel lines are much thinner.
I took the boat out (again no wake zone). I returned again, about 40 minutes. Glad I did. My bilge was full of fuel. The gas fuel line had a half inch split on top and was pumping out diesel fuel. Major clean up.
Here is where it gets tricky and I need someone's help. I decided that since the original line was much thicker (maybe the original clamps lost their spring is all ?) I re-used the original very thick fuel line with the new hose clamps. Long story short... This line developed a 1/4" split and sprayed fuel over the engine and bilge again.
My question: if this line is under so much pressure, why would Hino use rubber ? is an injector plugged causing extreme back pressure ? (I know nothing about injectors) splitting even the original hose ? Help ! Thx Dave
