Interesting Stuff in "Napa News"

[rjc]

Of course the Napa auto parts chain has their own newspaper which helps us do it yourselfers look for problems which helps us decide we need "parts". Anyway they do put together a good paper and this week I picked up one which described fuel pressure regulators. It was interesting that it recommended that you pull the vacuum line to see if gas is being sucked directly into the engine through a leak in the diaphram. I will be looking this weekend to see if the 4.0 fuel regulator is set up this way and to see if I have a pinhole in the regulator diaphram. rc

They do, and when they fail, that's what happens.... they dump gas into the engine, killing MPG and your O2's and possibly Cats after a while if you don't correct the problem.
