<html><div style='background-color:'><DIV>I was working on my '84 this weekend, and checked fuel pressure.&nbsp; It was correct, both with the regulator connected and disconnected.&nbsp; In comparing with another '84, however, I found that my fuel pressure leaked down almost instantaneously after shutoff.&nbsp; The other van held fuel pressure at the test "T".&nbsp; I checked for leaky injectors and found all ok in that department.&nbsp; Also looked for fuel line leaks and found none.&nbsp; Is there a check valve in the fuel pump that is not working correctly, or is there a check valve somewhere else in the system that I haven't found?&nbsp; If anyone's curious, the reason for the work was tha gas mileage had decreased to 10.1, immediately after installation of new transmission.&nbsp; I was trying to find if the shop had done something incorrect.&nbsp; Problem was O2 sensor failure, though this sensor was replaced last year and only had about 6K miles on it.&nbsp; Thanks in advance, everyone.</DIV>
