Just wondering if anyone can comment on the difference between the units.
Which check valve is this? I only know of a quick connection but not of a check valve on 990 injected models?

I just got off the phone to the manufacturer and they are the same units.
The details on the Dalby Moto site are incorrect and they do require the pump surgery of removing the internal check valve.
Have ordered one and should be here tomorrow

I have had one on mine since new and only changed filters at 30,000ks they were stained but still looked ok, replaced with gefr filters and carry a spare set on long outback trips just in case.

Cheers Boulder
Ive just fitted a set of gefr filters today, taken out the check valve and hopefully get the purge module tomorrow.
My filter has only lasted 13,500k's, just copped a bad load of fuel.
The inner filter looks spotless and new, the external one looked clogged!
The Safari makes life a little more difficult but hopefully should be good for a long time to come

Hear you with the safari tanks, we had trouble with both our bikes leaking where the pump mates against plastic and have fixed it with a cork gasket, was going to replace cork with viton rubber but the cork has never failed so just left it. Was a worry when Brothers bike decided to start leaking on the french line but lucky we had made a spare cork gasket when we fixed mine at MT Dare.

I just fitted a thick rubber gasket, hopefully Viton, that I got from Safari recently and two 3.5mm section O rings.
Hopefully it will last.

I wonder why is that neccesary?

I mean what if this check valve was omitted? The fuel would return back to the tank, when the engine would stop working. I understand the fuel is now more readily available to supply fuel to the engine, making it more easy to start, but would be simpler to not have this extra valve.
Cheers.

It keeps the fuel line pressurised but wont allow reverse flow.
The reverse purge wont work with this in place and why a new check valve is installed into the line to do the same job but still allow reversing.

So got mine and



Fitted up here



New check valve



Also added an extra filter on the crossover so half the fuel gets a pre filtering



Should be good for a while I hope

Ive been running with this RP module for a couple thousand k's now and so far so good except for one thing.
When cold, after sitting for a couple days, it takes quite a lot of cranking to start.
Up to the point prior to fitting its always been nearly instant start from cold.
Fine when hot though.

Anyone one else experiencing the same that has the module?

Not sure if the gasket I used was from the safari tank, got blanking plate from a guy through this forum and several gaskets came with it but from the look of it after a few years in place the gasket was quite damaged:

I've had mine for 2+ years. No issues. You shouldn't have any as it only reverses the pump. Is the check valve correctly functioning?
