The most efficient way to feed fuel is to let gravity do the work! Instead of relying on overcomplicated pick up systems in the tank, or running the risk of quarter tank issues from draw straws, simplify things with this sump kit from Sinister! Now, fuel is fed from the bottom of the tank via a large bowl to a 1/2" line that will ensure your pump will NEVER starve for fuel! This kit is designed to only work with aftermarket lift pumps with 1/2" lines, such as FASS.
