Bad Mileage

I would still recheck your pump timing to make sure it hasn't slipped. Oo.

Well I had lost my # to my cheap OF valve's anyways and had to get it from WadePatton so before I even drop the $$ on a new OF valve I'm gonna take the OE one off and check it and stretch it if needbe.

Well I still have not had time to disasemble the OF valve, but here's something I found out today.



When Chrysler repalced my return line they did it ALL the way from the OF valve back to the rubber line too... . ????



Well when the replaced the metal line at the overflow valve they DID NOT replace the OE overflow valve with 188,XXX miles on it. So I'm thinking something may have happened with it, and I hope to disasemble it soon and stretch the spring to see if it fixes anything. Wish me luck.

Well I had a chance today to recheck the fuel pressure with my OE overflow valve, and also a known good one (mine new one is still coming in the mail).



Looks like I'm in the market for a new lift pump. :{ Pressure's were about the same or a little worse than when I checked my pressure the other week.

Which overflow valve are you referring too? I have similar issues.
