All New Fleece Performance replacement under hood filter assembly for the Ford F250/350/450/550 6.7L Powerstroke! The plastic OE filters are prone to cracking and fuel leakage – eliminate the risk of a cracked filter with our billet aluminum cap assembly and billet aluminum quick disconnect fittings. Our drop-in replacement filter assembly locks directly into the stock filter location and utilizes a replaceable spin-on Donaldson filter that is easily serviceable. The kit includes an extra Donaldson fuel filter, further extending the time before you need to purchase an additional filter.
