Typically fuel line is rated for both gasoline and diesel fuel use. Have you verified yourself where exactly the fuel is leaking from? If it is just a hose, it should be a relatively easy fix dependingon its location.

Its the smaller hose that goes from the fuel filter to the engine I thing its call "fitted fuel hose" and its 38cm/7mmID. Someone said to change the fuel thermostat or the O-Ring! Where is the O-Ring located? Thanks

On the left side of the engine (from drivers seat), the fuel travels through this little clear in-line fuel filter thru a short black small hose that goes into this metal cylinderical gizmo bolted to the side of the block. It has about 4 other small black flexible hoses connected to it with small hose clamps. The white plastic part that the hose from the in-line fuel filter connects to is loose and leaking diesel. Looks like I need to replace this approx 2" long metal fuel dist. thing. Anybody know what it is, what its called, part number and or what it costs? Any special things I need to know to change it out?Can I bypass thefuel thermostat, how much does it cost and where can I order it?...and if I only change theO-Ring will it work? Thanks much in advance
