   [Modified (spell checks).]
   No need to pay the outrageous price for a complete Fuel Pump Assembly. I ordered one of the Quantum pump replacements (mentioned elsewhere here) PN HFP-397, Fuel Pump, EFI. $80 U.S. and free shipping. The Quantum site only has a pic of the removal of the three screws holding the cartridge assembly. No other pics, and no instructions come with the pump cartridge and filters due to multiple applications for their filters. Several filters are included with the kit since the same kit is applicable to a few other bikes. O-rings for the RE EFI are not included and must be purchased locally.    As measured, the smaller O-Ring:OD = 11.5mm, X-Section = 2.0mm
   As measured, the larger: OD = 12.7mm, X-Section = 2.0mm.   If you have a decent Seal and O-RIng supplier nearby, take the rings to them for verified measurement.   The whole assembly removal from the tank was easy enough once the tank was removed.   
   
1. Remove the three screws attaching the Cartridge Assy to the Pump base.
 
2. Pull out the Cartridge/Cartridge Holder assy. The visible O-ring may need to be removed from the pump base. I recommend you DO NOT re-use it, regardless of apparent condition. Your pump will leak.
   
3. Pull the cartridge out of its holder. Note the O-Ring at the top of the cartridge. I also recommend you DO NOT re-use!


4. Remove the filter assembly. It is a Press Fit to the base of the cartridge, so use pliers to remove if necessary. It's a very robust base, so it won't be hurt.


5. Remember which O-Ring goes where. 
6.  When pressing the new filter to the new cartridge some soapy water or liquid soap applied with a Q-Tip to the OUTSIDE of the cartridge outlet will ease the installation.


7. The installation is straight-forward.


8. Install the new O-Rings to the Cartridge/Filter Assy, and the Holder. LUBRICATE the O-Rings with fuel or an assembly lube. If installed dry, they can be damaged!


9. If the white sleeve comes off, remember it goes on the " - " wire terminal.


10. Press the Cartridge/Filter assy into the pump base. Very straight forward install. Route the wires as shown in their clips. Install the three screws.


11. The Pump assy-to-Tank O-Ring is FAT, so it's re-usable unless damaged.


12. The Tank Mount groove is poorly milled, and mine had paint blobs, and what appear to be clinkers from the welding embedded in the O-Ring Groove. Good thing that O-Ring is so FAT!

 The 5 each Fuel Pump mounting screws should have blue LocTite applied to the threads and be tightened enough to seat the base of the fuel pump assembly against the tank.    You're done!

Thanks, mates. :)
Wondered this morning if I had put the wrong PN in the post, but when I checked it was correct. Did find a few spelling errors to correct, though.  ::)

Based on a few recent comments elsewhere I should point out that the Quantum site has an excellent setup for choosing the correct pump for your bike, however the one(s) specific for RE is limited to the 500cc and only as recent as 2016.

Heloego, Where did you source your replacement o-rings?  I presume you ordered them unless they came with the new pump.  Thanks.

And there it is right in your opening paragraph.  Life would be so much easier if I would read first before posting.;-)  Now I know exactly where to get the new o-rings.  Sorry, and thanks.

Glad to help.

If you source locally like I did be sure to take the old ones with you so the vendor can measure them again as a backup and provide a good match.
As cheap as o-rings are it never hurts to snatch up a few extras "just in case".

Did your o ring supplier happen to mention which material your replacements are made of? We must consider the destructive properties of ethanol laced modern fuels. Anyway thanks for the DYI and other info . Super valuable.

I use Ethanol-free gasoline so plain ol' Nitrile rings fit the bill for me.For those who only have the ethanol crap available in your area, consider Buna-M or other options.

I believe you meant to say Buna-N.

Buna-N, also called Nitrile  is resistant to gasoline and alcohol and acceptable for static seals.

Silicone and Neoprene is not good with either of these fluids.

Viton is perhaps the best material but it is rather expensive.
