Jack,
Thanks for the observations. It's interesting that "crossovers" may not
be correct.....
I installed the Moss kit to convert the late TD filter to a spin-on
because everyone assured me that modern spin-on filters filtered better.
Well, with one exception, actually, and that was FRAM to whom I posed the
question in a letter and supplied a SASE for their response. It's only
been 10 months, so there may be one forthcoming.
Moss supplied a Fram 3600. That orange filter clashed with the red
on the engine, whereas the old Tecalemit green was, at least, original.
Fortunately, Duplicolor import auto spray 88-00906 Hampsted Grn MC is a
reasonable match to the Tecalamit color.
Based on discussions of filtering ability (in the TD there is no need
for a check valve) in the list, I bought a number of Wix filters and
sprayed them with this paint. It's a bit bright, but not too bad, and
certainly better than orange or white.
