I just wish you the luck that you never have the Series 1 fuel pump issue. Mazda saw the problem and switched to a different pump design and manufacturer for the Series 2 fuel pump. And for all those RX8 owners worldwide, that have had this problem, including Charles of BHR, they know it is real and have found various solutions to fit their driving needs. Some have had success with DW and other pumps, some have had success with installing a Series 2 pump. lol
And if you get your kicks dissing on me, no problem. I can take it and let it roll off my back. I am not going away folks, so enjoy !
I don't get my kicks dissing, you just state things as fact and make them out to be something they are not. Like the way you talked up the DW pump like it was the answer to the S1 fuel pump "problem" and then you ended up getting rid of it even though others tried to explain to you why a higher flowing pump is not needed on a NA RX-8.
Then you constantly bring up your vast rotary history as if to toot your own horn and insinuate that you have a lot of experience repairing RX-8's when really you have a lot to learn.
Every electrical component has a failure rate. Yes the S2 pump assembly is seemingly better but that doesn't change the fact that 99% of S1 RX-8's owner don't have a premature fuel pump failure. The fuel pump is not something that should be replaced unless it is actually having a problem and should not be on your list unless you are having a problem with it or unless you plan to track your RX-8 or add forced induction.
The S2 assembly IS better. Every component does have a failure rate.
I also agree that a higher flow fuel pump is not required if NA.
The S1 fuel pumps DO have a significant failure rate. Only it's not the pump itself that fails. Yes you lose some pressure over the years. That much is expected from an old pump.
The failure point on the S1 is the connection at the top of the housing assy. It cracks, usually around 80k. Does it happen with everyone, No. Does it happen enough to state it, yes.

You are not dealing in reality with regard to the Series 1 pump. Mazda got it, but you don't. I am wasting my time discussing it with you. THE END

The reality is that you have no clue what so ever how many S1 pumps failed prematurely so you can't discuss what you have no clue about, yet you like to make BS blanket statements about things as if you have some information that others don't. Before you were all about the DW pump, now you are all about that S2 pump life because others here educated you in the fuel pump thread. THE END.
Some who have had the Series 1 pump problem have found success with DW pumps, and still do. For my style of driving, ultimately the Series 2 pump was a better solution. You say i don't know how many series 1 pumps have failed, well likewise you don't have the numbers yourself to say they don't fail. And it is not just high mileage RX8s or cracked connectors that will cause a sudden shutdown. As the pumps age they are more prone to overheating caused failure seen in cars with lots of sustained high-load driving, and the pump overheating and sudden shutoff is worse at low fuel tank levels.
You can argue all you want, but Mazda got the feedback, and changed the pump for the Series 2. I got that straight from a friend at MNAO and also my Mazda regional rep, both of whom I have known for years . I think they know better than you. Deny reality if you wish on this matter. I will add the fuel pump to my Series 1 maintenance list for anyone who asks. I will take the RX8 club name off that list's heading unless a moderator wishes to add it.

Your friend at MNAO and a Mazda regional rep have engineering info on why the Series II fuel pump was changed? LOL, come on man, "you ain't got to lie Craig".
Never said that, but MNAO and my Mazda regional rep do have feedback from owners that have had to change Series 1 pumps due to failure, some early enough to have been changed under warranty. 9krpmrx8, You can deny the facts till you die, I really don't care to go on with you over this. Enough said, I agree with BigCajun, move on.
Yeah the filter issue is weird, I have seen high mileage pumps with clogged filters (mine) and I have seen several that were clean as a whistle. I chalk it up to premix in my case. I can only go based on what I have seen and I have seen many local RX-8's go north of 100k on a fuel pump without issue.
I mean if someone wants to replace it then that is their decision. But I think it's a bit of an exaggeration for some to imply to new owners buying a used RX-8 that the fuel pump is a ticking time bomb and that there is a need to replace it if you are not having any issues with it.
And according to the service schedule I have from Mazda for a 2004 RX-8, oddly, they recommend replacing the fuel filter (which you can't as you know) at 100,000 miles. So you could take that as them recommending the fuel pump assembly be replaced at 100,000 miles.
The filter/sock on the series II RX-8 is a serviceable part so maybe someone caught that.
The service schedule for the 2009+ RX-8 doesn't even mention the fuel filter at all and as I said it is a serviceable item that you can buy separately. This is why trying to figure why Mazda does or does not do certain things is a waste of time, . I have a FSM for a 2009 and a 2006 so I will look tonight and see if the FSM differs from the service schedules on the Mazda site. I doubt it will though.
