[Mgs] Oil bummer

[Barney Gaylord]

I don't know if the current Moss oil signal hose is Teflon lined.  It 
doesn't say that in the catalog listing.  Time to ask Moss.  Got your 
ears up, Kelvin?

It seems like such a trivial thing to do in production, and shouldn't 
add much to the cost of the raw hose (compared to total cost of 
manufacturing the hose assembly).  However, while fuel hoses run 
under 10 psi, the oil hoses run up to 100 psi, and hydraulic clutch 
hose runs about 250 psi, and brake hoses more like 500 psi.  Brake 
hoses have thick wall and very small bore size (which is okay for 
very low flow rate).  Clutch hose has larger bore for higher flow 
rate (for quick clutch return).  Fuel hoses have much larger bore and 
thinner wall.  These are all different creatures, so they don't 
necessarily all come from the same production factory.
