I have a 1965 johnson 18hp in which had a hardened (to the point of it cracking off with slight pressure) hose/tube that runs from the pulse fitting (oppisite the fuel pump) to the intake manifold to the left of the carb. The nipple on the fuel pump side is very small (1/16 inch or smaller) while the other end is quite a bit bigger (1/8 inch or larger). Is the oem hose pre stectched for the different diameters? If not, can I get away with over the counter general hose replacement? I also have a 1972 evinrude 18 which appears in similar condition.
There is also a hose from the lower portion of the crankcase to the upper ( I suppose to help lubricate the upper bearing) that also appears hard and probably brittle.
