Asked by Sep 16, 2013 at 01:49 PM about the 1998 Subaru Legacy 4 Dr L AWD Sedan

Question type: Maintenance & Repair

I have replaced battery terminals and checked battery and alternator they are good.
I replaced Spark Plugs about a month ago. The power steering pump does leak and I have a slow oil leak from the valve cover gaskets.

I would take a look at the operation of the fuel pressure regulator....the way the diaphragm allows more fuel, then collapses to a default location....perhaps the diaphragm was sucked in pieces through the vacuum line, partially obstructing the vacuum flow....I'd take a serious look at the fuel pressure regulator~

always go with silicone replacement hoses will NOT degrade, cost about four times more....but worth it~

you should be able to cinch down each of the valve cover bolts a scoach~

If you're sure it's fuel pressure you're losing, the first thing I'd check and replace would be the fuel filter. Valve cover gaskets and the power steering pump shouldn't have anything do with that issue.
