i changed all the lines and still have air. i saw a new sediment bowl on a site but forget that site. is there a solid filter without a sediment bowl. thanks i don't want to take it off the road and drive my 4.9 f150
If you just want a solid-bottom spin-on fuel-filter with an integral drain, then cross-reference that NAPA number in the previous post and you should get a bunch of possibles on this site :

If you want a genuine "sediment bowl", then that is a horse of an entirely different color.
If that be the case, there was a company on E-Bay that had a bunch of genuine LUCAS glass-bottom water-seperators/sediment-bowls with drain-valve and NO FILTER; I bought a lot of four of these units and currently have one on my personal truck and am in the process of installing the other three on some of my other trucks.
A GoldenRod is also a good sediment-type filter with a large capacity bowl that also incorporates a filter cartridge.
