FASS Fuel Flter Delete Install: Duramax LML #DFD-4000
Thoroughbred Diesel, "The factory fuel filter on the Duramax powered engines is not only difficult to replace because of its awkward positioning, but is also expensive. For those that have added an aftermarket fuel filtration system, or a lift pump with an integrated filtration system, such as FASS, you no longer even NEED to have this troublesome filter on the truck. FASS now allows you to eliminate this by installing their Duramax Filter Delete in place of the stock fuel filter. As a bonus, this comes pre-equipped with a gauge port for those that wish to monitor fuel pressure. Here is how to install fuel filter delete."
