🔍 Silver Aluminum Fuel Filter Cap for Ford 2003-2007 6.0L Powerstroke Diesel F250 F350 F450 F550 Super Duty Review

Poorly made test port plug has nothing to the bottom and won't screw tight. Also, fuel leaked from the inspection port despite the presence of thread sealant, which the truck was given time during the night to cure the truck on the stand.

cap is excellent no leaks when using teflon tape. No O-ring is included, but you can use your old one. After screwing by hand, use a 15/16 wrench and do not tighten more than 1/16 when it stops turning, otherwise it may crack. Just screw it tight and it won't leak. This is a trial cap. If you want to run the gauge on fuel, buy a set of electrical gauges and install them in the test port instead.

Everyone who says that the plug has no sealant and does not leak is correct. However, it's very easy to pull it out with an Allen wrench and coat it with Teflon, making a big deal out of nothing. It didn't affect me in any way because I dragged it to add a sensor. However, if you buy something new, you don't have to modify it, there's no more pride in the workmanship. 3 stars
