Pure diesel fuel fed into your injector system is the starting point for everything in your GM truck. Impurities in your diesel or inadequate fuel flow can cause expensive damage to your engine and injector system. Factory fuel systems are not geared to support higher horsepower and are prone to issues causing unneeded wear and tear along with a slow decline in fuel efficiency. Improper diesel fuel pressure and low purity can cause engine damage and lower your fuel economy. Upgrade from your stock system to FASS's No Drop Series Fuel System Kit and improve both diesel pressure and filtration. This kit starts with a Titanium Series Plus fuel system offering advanced filtration that removes water, air, and debris from your diesel fuel at a 2-micron rating.  Plus, with the included easy-to-install sump pump you can rest assured that as long as there is still diesel in the tank your pressure won't drop.

Now with an added Heat Sink to the Titanium Plus line of FASS Fuel Pumps. This Heat Sink lowers internal motor temperature by up to 20 degrees, extends the life of the already proven million-mile motor, and adds a clean, upgraded appearance to the system.

What GPH do I need? This all depends on the horsepower of your truck and your future goals.

  • 140 GPH- Stock up to 700hp. If you haven't done or plan on any, or very minimal, modifications to increase power.
  • 220 GPH- This is for 700hp to 900hp.
  • 240 GPH- This is for 900hp to 1200hp.

Comfort and durability

Socks work really good. I have very rough and dry feet that tear up my bed sheets. They hold up to my destructive feet. They are soft and comfy!

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.
