Fuel Mileage Drop?

It's been way down since the HG install. Could the winter blend cause a 100 mile loss a tank? Seems extreme.

I have no signs of a leak. The oil doesnt smell of fuel. I havent seen any spots in the driveway or anything.

The fuel filers are 8K old and are getting replaced this weekend.

Thoughts?

that seems a little extreme. Are you driving it a lot harder now that you got the HG's fixed?

I bet it has something to do with the new rails and HPFP. Alot more volume through those. Might be throwing the milage calc off.

Got a parts list for me yet Jesse

I suffered a similar loss after I had my HG's replaced. Mine was done by Ford under warranty with all stock parts. A year later now, and we never could find the problem. It sucks!!

The problem will be trying to pin point the cause of the fuel mileage loss since there was alot more work done than just gaskets, from what I have gathered.
