I am needing to remove the filler tube to access the spark plug ports for the dreaded re-boring after a blown plug.

It is apparently just a pressure install with an o-ring and I have tugged and wobbled but no luck. Is this correct?

(1999 E250 with 5.4L Fuel)

 

VIN L or M or Z, I picked L (the 8th character of your VIN)

 

"L" is correct, but this is for oil filler tube. I am seeking the Transmission filler tube removal please.

Transmission dipstick tube and filler tube is the same tube.
