Also, give Steve a call at Tousley Ford.
Steve's # in the FAQ-Duratec Maintenance I'm doing a BIG old rebuild on my car, so I'll be doing coolant flush, tranny flush, oil/filter change, and a complete UIM/LIM manifold rebuild this summer, but the parts for all of that came out to about $100. That includes all gaskets, manifold to fuel rail seals, o-rings, and spark plugs. Just give Steve a call, he'll know what you're looking for, specially since him and I walked through all the parts this morning. BTW, list price for all my parts was ~$170.
