in case those guys are off-line, i'll answer... you're belief is correct; the filter is not there. The line you mention should be in two pieces, and the filter should be in the middle, the 90 degree part pointing toward the white cap you mention. That white cap is the old style plunger on the lift pump. This is what gets the fuel to your injection pump. The white thing unscrews (ccw), then pumps up and down to prime the filters, etc. The new, cheap bosch model ($13 from autohausaz.com) just screws on and is a very easy/gratifying fix.
You can pull the fuel line off of the right side of the lift pump, stick an inline filter on it, then find a couple of inches of the same fule line to connect the 90 degree side to the lift pump. Cheap and easy, and you will have corrected a serious wrong (unless the p.o. put the filter somewhere else). Don't forget to round up a couple of hose clamps too.
