It looks like the same pump that MRP are selling (see the link in their thread above), if it is the same one then it should be a good bet. It's within pennies of the MRP price once you include the RX8OC discount.

How do you get the existing pump out without a special tool?

From the service manuals I see that the RX8 has a saddle tank with the pump in one side and uses a siphon to get fuel from the other tank.

How does this work if a high flow pump is fitted? For example, does the siphon work with the higher flows, do the aftermarket pumps cater for this or is the fuel in the other side useless?

Depends on if the syphon has been modified to cope with greater flow or not. Arnie_O had problems with his fuel pump and he modded the syphon according to a guide on RX8 club. I'd link to it but I am on my phone.

Your still going to need a fuel pump tool, plus a rattle gun helps.
There are two black plastic tabs that you need to brake off to allow you to undo the ring

Just read the description of this:
http://www.ebay.co.uk/itm/WALBRO-255-FU ... 415f512bf4

"Note: The OE siphon assembly cannot take the elevated relief pressures as it stands. The pop-off valve on top of the syphon must be melted on with a hot piece of metal or something similar to keep it in place."

anyone done this, know what they are on about?
