i've been reading all these old posts and filling your spin-on with ATF seems completely acceptable, even recommended. this sounds like a completely ludacris thing to do but i assume it isn't, seeing as a few of you seemingly trustworthy and knowledgable guys condone it. my question is why should i do this rather than filling it with diesel? while i'm at it, another question:
what the heck does the ALDA looking thing on my IP do on a non-turbo 240?
and another:
why can't i get that last little air bubble out of my primary? (clear) fuel filter?

ATF lubes the IP.

The ALDA on an N/A car increases fuel flow in relation to a decrease in atmospheric pressure, if one were driving from the seaside to the mountains, for example.

A little bubble or space at the very top of the clear filter is OK.
