What the fuel filter you put in should look like This is pictured upside down. Look for SOMETHING that looks like this that, looking into the engine bay from the front, is located directly to the left of the engine. It'll have a hose coming into the black bottom and a hose coming out of the metallic top.
on the topic of fuel filters, thanx for those great installation instructions you gave, j spec. i changed mine to a 300zx and it was a really painless procedure (cept gettin gas all over my hands). so far no problems except i think the mixture runs a little rich so the engine idles sometimes at startup at over 1000 revs. i think i'm just imagining a diff in performance tho.
