  • Extra Info:

  • When you start modifying your diesel powered truck for more power, you’ll quickly find that the stock fuel pickup tube is inadequate. And on many Duramax, Cummins, and Powerstroke setups, your lift pump can even start to draw air into the lines around 1/4 tank. That can create disaster when you’re at the track or on the trail with 0psi of fuel pressure and your injection pump seizes.

    The Sinister Diesel Fuel Tank Sump Kit uses a massive 1/2 inch fuel line to eliminate restriction to feed the biggest aftermarket fuel pumps and injectors with the fuel they need on high horsepower builds. This Fuel Tank Sump Kit is CNC machined from Billet Aluminum and features a durable anodized Sinister Diesel blue finish for extra protection and style. And like all Sinister Diesel parts, it is manufactured and tested at our California headquarters and comes backed by the legendary Sinister Lifetime Warranty.

    Note: This kit requires the use of an aftermarket lift pump
