Original NOK Manufacturer brand pump seal used in the Barry Grant 400,280,220 fuel pumps and Magnafuel pumps. These seals are used in the pumps before they changed over to the new "walrus" design in mid 2006. They have a LARGER OUTSIDE DIAMETER than the smaller OD Walrus seal and will not fit into the newer body. If you have a 2006 or newer pump with the newer design seal, please see our other add for the newer Walrus design seal. This seal also replaces Magnafuel and several other brands of pumps using the NOK seal. This is a COMPLETE seal kit for the 2006 and older pumps ,one kit will fit all models, as it comes with the differant model size lower plate orings as our kits have always included. We also have available the specialty Tri Groove socket for removing the security bolt from the lower housing if needed and can offer special pricing with seal purchase. Check out our other add for replacement motor bearings. We also have several BG5000 reseal kits. We have been supplying this original equipment seal locally since 2000 and worldwide right here since 2004. Thank you for the many repeat customers we have had. Please beware it has recently come to our attention that our adds for the kits are now being copied and pasted by a few new sellers and have OUR product reviews linked to them. We take this as a compliment but have no guarantee as to the same quality of their kits.
