S/S Chevy Fuel Pump Bolt Kit 12pt.

The S/S Chevy Fuel Pump Bolt Kit 12pt. is a precision fastener upgrade engineered for Chevrolet fuel pump assemblies where reliability and material integrity matter. As a mechanic who has sourced countless OEM replacements, I've seen fuel pump fastener failure compromise entire fuel system performance—and ARP's stainless steel solution eliminates that vulnerability. This kit is essential for any serious Chevy engine build, whether you're refreshing a stock fuel pump or supporting a modified carburetor or fuel injection system that demands absolute security.

Manufactured from premium stainless steel with 12-point head geometry, these bolts resist corrosion, vibration loosening, and the thermal cycling that plagues standard hardware in fuel pump mounting applications. The 12-point design distributes load across more contact surfaces than traditional 6-point heads, reducing strip-out risk during installation and torque-down—critical when working with aluminum fuel pump housings. ARP's manufacturing tolerances ensure consistent fit across replacement cycles, so you're not chasing fitment issues during reassembly. Stainless steel also won't leave rust bloom on your fuel bowl or contaminate fresh fuel, a detail that separates quality fasteners from hardware-store alternatives.

This kit benefits anyone performing fuel pump replacement, fuel system restoration, or any modification that requires breaking into the fuel pump mounting boss. Whether you're working on a vintage Chevy small-block, LS swap, or carbureted street machine, stainless fasteners eliminate future corrosion headaches and ensure your fuel pump stays secure under sustained engine vibration and heat cycles. For off-road, marine, or high-vibration applications, the 12-point head and stainless construction provide the margin of safety that separates a one-time installation from repeated comebacks. Always pair these bolts with a torque wrench and follow your fuel pump manufacturer's specification for optimal clamping force.
