Radium Engineering Multi-Pump Fuel Surge Tank O-Ring Service Kit | Universal (20-0088)

An MPFST that gets opened deserves fresh seals going back together.

The Radium Engineering Multi-Pump Fuel Surge Tank O-Ring Service Kit is the complete seal refresh for the MPFST: every O-ring the multi-pump surge tank's assembly uses, in fuel-rated elastomer, so pump swaps, staging changes, and periodic services reassemble on new seals instead of reused gambles.

What You'll Feel

• The MPFST reassembled leak-free after pump services and staging changes
• Weeping joints actually fixed, since the O-ring is almost always the answer
• One kit covering the whole tank, no chasing individual ring sizes

Features

• Complete O-ring service kit for the Radium Multi-Pump Fuel Surge Tank
• Fuel-rated seals compatible with gasoline and E85
• Covers the MPFST's serviceable sealing points

The Details

The MPFST's strength is its serviceability, with pumps adding, swapping, and staging as builds evolve, and every disassembly is a seal inspection by definition: rings that show nicks, flattening, or swelling get replaced, and the honest shop replaces on principle at major services since seals cost minutes while leaks cost weekends. Standard ORB discipline applies at reassembly, every O-ring lubricated with O-ring lube, petroleum jelly, or oil before threading components home. Keep the kit with the MPFST's spare pump hardware and services stay one-session jobs.
