DIY filter rock guard

I like to use the long cat ultra high effect filters or some times the long Baldwin filters.

by the time I get to service intervals….i get a few rock chips which sometimes goes to bare metal and once did a pin hole leak.

was walking thru the homedepot hardware department and saw these rubber sewer drain type pipe joints

bought a 3” to try on my cat ultra high effect filters and a 5” to try on the amsoil by pass or cat high efficiency oil filter …just to size them out.

the 3” fits perfect on the fuel filter with some hand lotion as a lube and a few light taps with a rubber mallet.

for the oil filters will try them later today.

my truck has 37@ tires and 4” lift …so even with that + 7” fuel filter tip height increase…still get occasional rock chips.

maybe this will help.

No way in hell would I run a filter that hangs that low. That's just asking for trouble. I don't even like how low the stock motorcraft filter hangs.

Yeah I think I would be relocating that thing or perhaps rotate it 90 degrees.

for reference, the center of the axles are about 18" from the ground and the bottom of the filter is pretty close to in line with that.

its probally higher off the ground than a stock oil filter

Are you sure about that? In the photos it appears to be noticeably lower than the radius arms, which would put it below the level of the front axle. I realize photos may look different from reality, but it doesn't look anywhere near 18" from the ground. Just looking at it, it appears to be much lower than my stock motorcraft filter.
