early 99 fuel filter replacement-rough running

[dark cloud]

I just replaced my fuel filter with a NAPA gold 3818. I was told this number
superseded the previous 3518 stated in a bunch of threads about fuel filter
replacement. The new 3818 has the fuel filter cap built onto the fuel filter.
Waited the minute or two for the filter to fill up afterward.
Seemed pretty harmless, out with the old , in with the new. Start up the
engine and it "stumble s when I step on the acclerater( in park). Going out for a drive to see what's up. Hopefully I make it back.

Stumble no more! Problem corrected itself with run time.

Just wondering if u had any leaking problems?

[dark cloud]

No leaks. I checked that out before starting. Seemed to get better with a little run time, probably not enough fuel in the system.

Just letting u know check for leaks after u drive it i had no leaks then after driving i did with that filter. And keep your old cap because the wix one doesn't work with the stock motorcraft oem filter.....

Fuel pump doesnt run as long as the glow plugs. Turn the key on and wait 15 seconds, then off and on again. That should fill the bowl when changing the filter.. What
happened is the bowl was not full
when you started it and you pushed air to the injectors like when running out of fuel. It
will cure it self, but complains when doing it.

tell me if the filters doesn't leak after like a day because i did mine didn't leak when i started it and then i replaced my gpr and there was fuel in the valley of the motor and around the wires. just seems to drip fuel doesnt spray it out...

[dark cloud]

No leaks around the lid, or in the valley a day afterward. New type filter
came with a o-ring and a square seal for the cap or lid. Thanks , dmd and
tylerwitt.

No problem i got a new wix free of charge so i'm gonna see if i didn't tighten it down enuff. I'm gonna make sure she super tight. It just drips fuel doesn't spary just if u havent feel around the front of the bowl closet 2 the cab and if u got no leaks maybe i didn't wrench on it enuff.
