My son has my old 1987 300D Turbo (240,000 miles so far). I couldn't find an exploded diagram on this site so here goes my best description of what I think we need. 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? Thanks much in advance. PS are there any exploded parts daigrams on this site?
