Description
Radium O-Ring Service Kit, Standard FST
Application: Radium standard 4" (102mm) diameter fuel surge tanks – Single Pump FST, Dual Pump FST, External FST and FST-R
Part Type: Fuel surge tank O-ring and gasket service kit
Part Number: 20-0087
Radium O-ring service kits include the seals needed to reseal the top and bottom caps of Radium fuel surge tanks. The 20-0087 kit covers both generations of Radium's standard 4" diameter surge tanks.
Early tanks sealed the top with a formed gasket, while later tanks use O-rings for the top and the bolts. This kit includes both styles, so whichever generation you are servicing, the correct seals are on hand.
Key Features
- Covers Two Generations: Gaskets and O-rings for early and later standard 4" FSTs
- Complete Reseal: Seals for the top and bottom caps of the surge tank
- Bolt O-Rings: 16 small O-rings for the M5 cap bolts
- Genuine Radium: Factory replacement seals for Radium surge tanks
What's Included
- 16x Small O-rings for M5 bolts
- 2x Large O-rings for canister
- 2x Gaskets for canister and bolt holes
Important Notes
- Reuse the same seal type that was removed from the tank – gasket and O-ring styles cannot be converted between
- Not suitable for Radium 6" multi-pump or high-volume surge tanks – these use the MPFST O-ring Service Kit (20-0088)
