4500 Series Tank Sump
In addition to being the only 45” tank sump in the marketplace, the 4500 is also PCI’s most popular and versatile tank sump. Our 4500 Series tank sumps are constructed of 100% fiberglass and offer long-term reliability without deforming or cracking. This provides one sump that works for all single STP applications. Exposure to fuel will never void our warranty.
