O-ring gives me hell for 5 hrs.

Went for a drive out in the country, stopped at a store, came out around ten min. later and car wont start. Lift up flapper and cranks rite up and I go home. Little diagnosing and come to find out I am losing rest press. Goes to 0 as soon as i turn key off. Off comes the fuel pump and check valve, nope, accum, checks out good to. Freq. valve must have blown out, nope. Decide to pull the fuel head reg, and there it was. Such a little part to cause such misery. Glad its fixed. Drive on 911!

I would have guessed check valve, i've had two instances of that failure. Good on ya for fixing it so quickly. I no longer have CIS but DME, trouble free so far except for a bad fuse....
