Question In-tank fuel pump upgrades?

Does anyone know of any in-tank fuel pump upgrades for the RX8? I'd rather not use an external pump if I don't have to!

Thanks

hey dude, i replaced my stock pump with a walbro. it will fit just fine, well maybe once u put the rubber gasket circle thing back on, then it be kinda tight. but thats ok cuz extra seal is better. just open the pump casing and everythin should be simple. also u have to splice wires and make sure u use heat shrinkin tube to cover it all up. anything else just ask me. bye for now

Would definitely like to know which pump you ended up using; I've converted my system to return-based with external FPR so need to get rid of the stock pump asap! Did you use the FD walbro drop-in?

Thanks
The Mazsport pump is actually a plug and play kit that uses the factory connectors and lines. The system utilizes a rising rate regulator and converts the factory system to a return system. The pump is a proven reliable unit and will support more than 400rwhp in rotary applications. Because we have done most of the work it requires about 1.5-2 hours for the complete install, we have them in stock and ready to ship! On a side note, Mazsport does NOT use Walbro pumps.

Thanks Scott, but I actually need a pump with no regulator built in; sounds like a great kit though.

i heard that Walbro pumps may not be very dependable. From reliable source. But that is only an opinion. I wish more choices where out there. Mazsports kit looks real good and I may end up with that.
