Just ran out and looked at my 90 out of curiosity. It has six lines
all coming out of the top. The CSV one is the one 'closest' to the
engine, by the way, but I bet they are all the same, considering the way
these heads used to run 5 or 6 cylinder engines.
They obviously aren't the same metering heads, since on a picture of
mine of the CISE metering head there are five regular fuel ports, and a
blank space where a sixth would be (on a 6 cyl engine), and the CSV line
taps off the side of the metering head.
Personally, I think the CSV is overrated as a source of trouble -
air/vacuum leaks, injector leakdown, faulty temp senders, bad check
valves, poor grounds and such are much more likely culprits.
On the car originally in question, it might make sense to test the CIS
temp sender in ice and boiling water to see if it still works right.
