2004 RX8 Fuel Pump Removal DIY Part 1

[@matthewparent2102]

The 04 rx8 is the first car I’ve ever done my own work on. This video and the pt.2 saved me not eating for a few weeks, quite literally. Much love and thank you very much! You’re appreciated more than you know

[@johnnyg2392]

Thanks so much for this. Car smelled of exhaust fumes. Mechanic discovered and pointed out fuel pump leak. Saw the gas around that area. $1000+ estimate to have repaired. Ordered part online $150+. Refundable deposit on fuel pump remover tool kit rental at NAPA/AutoZone. Car up and running. No leaks. 2007 RX8. Thumbs up!!

[@michaelmcnaught6536]

Bro, I know this was 8 years ago. But have an 07 Rx8 that brought me here. Believe the fuel pump is the problem. Will turn and crank. Will ALMOST sputter to life but won't get where it needs to fire and start. Tried to deflood it, first time I was able to pull the fuel pump wire, turn the key and crank it with a little depression of gas pedal, connect the wire and it started right up. Second time, it did not work. Thinking fuel pump is toast

[@arnold9038]

Nice and pretty detail video. Thanks for sharing. Got a quick question though - would u be able to show how exactly that needed to be done with the fuel pump change itself to the unit that is hidden from the video? I am planning to change to Walbro 255 pump and just not too sure if i can DIY without any much of mechanical knowledge. Thanks.

[@mrdiez8496]

Did u ever get an answer? I'm curious as well.

[@arnold9038]

+mr diez no... i bought Walbro but didnt change it as my original one works just fine after some cleaning up by my mechanic .... dirts clog up there.....

[@sheldonarthur4754]

Rx8 has a return less system, the other line is a siphon from the other side of the tank.

[@Gluluman]

what prompted you to change the fuel pump or how do you know the fuel pump needs replacement?

[@MTBfixHQ]

Car felt just a little bit sluggish in the high rpm's and the fuel filter was only $80 so I decided to change it to see if it would make a difference. Turns out it did help my high rpm's a little bit for sure so it was worth while for me

[@Gluluman]

@@MTBfixHQ - thanks I got an RX 8 and it's a super duper head pain . can wait to flush it down the tube

[@MTBfixHQ]

@@Gluluman Sorry to hear that, my rx8 treated me extremely well and honestly miss the hell out of it. I was in the market for a sports car 2 months ago, i tried the frs/brz/wrx/civic si/s2000/350z to name a few and none of them drive nearly as good as the rx8 on the road, rx8 is so comfortable and handles amazing I was going to buy another one but no point because winter is about to start and I hear there is a chance mazda will be announcing the rx9 soon :)

[@Gluluman]

@@MTBfixHQ well mine not too bad either until something goes wrong with it and cost me an arm and leg to fix at my local Mazda, specialist, or may be i am not a car guy. If you want mine you can have it.

[@chrislg4519]

@@MTBfixHQ Great info 👍Did u ever premix 1/2-1 oz 2 stroke oil per gallon with high 93 octane to lube seals & rotors? Im worried premix oil could clog fuel filter, plugs and/or Catalytic. Also what crankcase oils did u use? I have 2005 Thanks 🙏🚘🚗

[@R35P3T0]

Maybe you can help me. I been having trouble with my rx8. When it's cold it will start with no trouble. But when it gets hot. Sometimes it won't start, till I wait a little for it to cool down. You think it can be the fuel pump?

[@MTBfixHQ]

this is a common problem when your engine starts to lose compression, its very likely you will need a new engine get a compression test done

[@tonys3112]

Had same issue with my 2006 turned out to be fuel pump. What I found was the sound the fuel pump makes when you turn on ignition. No sound no go. The second thing was would start couple time then start and just die. It was random Putting in new pump tonight. Thanks for the how to videos great help

[@michaelvanatsky4058]

Rather than destroy the locking tabs, i inserted expired credit cards between the tabs and the ring to allow the ring to turn. Then the tabs still work on reassembly.

[@MTBfixHQ]

good tip! also I never broke any of the tabs :)

[@gunfighterdrummer]

My 2005 wont turn over. Alt and batt are good, spark plugs are clean. Someone suggested reolacung the fuel oump. Could it also be the accending shaft position sensor??

[@rapachannel8359]

Hi Jack I got a Mazda rx8 2004, my car won't start and got no crank, battery is good.. jus wondering if u know anything about this prob of no crank/no start. I dnt knw what can b the problem. If u can help me plz

[@jschroeman]

Rahul Sharma Hey man, I also have an 04. Have you tested the starter? The original starts are too small and are prone to failure.

[@sriram042000]

How did you know it was time to change the fuel pump? I recently started experiencing some issues on long drives where the rpms would suddenly die on me. When I pulled over and restarted the car a couple of times, all would be fine again. I'm not sure if that means the fuel pump's on it's way out but I'd like to do some PM before it's catastrophic. Does that sound like a fuel pump symptom?

[@MTBfixHQ]

sorry I couldn't tell you for sure, but have you changed you ignition coils ever? sometimes they can act up when they get hot if they are old, i did not experience those symptoms with my rx8

[@sriram042000]

Jack Sadek Yes I change them every 30k miles. The last change was about 20k miles ago. Plus I've had coils go on me before and they weren't like this.

[@MTBfixHQ]

sorry i dont know what to tell ya, it does seem the fuel pump can cause that so it might be worth it to just change it, you can get a oem replacement pump from BHR for $80 i think

[@sriram042000]

Jack Sadek Ok. Thanks Jack!

[@SKITTL3Z37]

+p.s sriram I'm having exactly the same problem and I'm gonna change mine pretty soon here. did you ever get it fixed? What was the problem?

[@DIYAllManphKDWzpeedengineering]

Do you know where the fuel filter of the Rx-8 is located? Inside the fuel tank? is there also a fuel filter outside the fuel tank? Thanks

[@MTBfixHQ]

fuel sock located at the bottom of the fuel pump assembly is the only filter for the rx8

[@DIYAllManphKDWzpeedengineering]

@@MTBfixHQ Hmmm...thats weird, that primary fuel filter offers little protection for the fuel injectors....traditional fuel filteribg systems have that primary filter then an inline high pressure side filter

[@MTBfixHQ]

@@DIYAllManphKDWzpeedengineering There has been a discussion about this on rx8club, its the only filter for the rx8, read through it www.rx8club.com/rx-8-discussion-3/fuel-filter-location-198704/

[@goodfela420]

Man guys i had power loss at top end and after look at all else i went to fuel pump. It had a very slow leak on top and i hoped it the pump was weak equaling my power loss. After fighting off lockring with taps from hammer and GIANT screwdriver for 25minutes... It came off. After replacung pump the car chirped jumping into second gear... Couldnt b happier. Carquest lifetime pump from advanced auto $215. Rated well above specs. Power band is back in full swing!!

[@MTBfixHQ]

Good to hear! It's always a satisfying feeling when changing a part actually helps :)

[@ESquaredSolutions]

Also, FYI there was a recall for a part of the fuel pump assembly causing leaks. consumerist.com/2016/11/15/mazda-recalls-rx-8-sports-cars-over-risk-of-fuel-leaks/

[@NAH-vk6pk]

Flathead screwdriver and rubber hammer works better than the rental tool. The one you made is much better...

[@adrianzavala1729]

How do I see if the filter is clogged?

[@75thTheDude]

is it normal that the car smells like gasoline like crazy after reparing it? I do everything myself on the rx8 like replacing clutch, brakes, exhaust and some other stuff but had this done by a mazda shop because mazda did a recall for the fuel pump. smells like that for 3 days now.. loved the smell of leather before

[@MTBfixHQ]

Depending how messy they were fuel smell can stick around, I was pretty clean when doing it so I never had any fuel smell afterwards, not that I could tell anyways. Remove the seat and cover to see if there are any leaks, also mention it to the shop that did the work

[@75thTheDude]

Jack Sadek thanks for the fast reply. I removed the backseat and noticed that they spilled gas over the metal plate that sourrounds the pump.. they kinda cleaned it but not too much. After cleaning it myself the smell gets less and probably just disappears.

[@MTBfixHQ]

Good to hear, only takes a few drop of gasoline to make the car stink of it

[@75thTheDude]

Jack Sadek just to give u an Update, everything was fine with the car. When the 8 was empty i just filled it up with 25 litres. Yesterday i completly filled the car up and today it smelled really hard and gasoline was all over the ground below the fuelpump. I gotta visit mazda tomorrow.. hope they take care of the mess they made

[@import4lifehaze217]

[@caesarcruz6427]

[@TamNgo84]

What was all that noise in your engine bay?

[@MTBfixHQ]

the high pitch humm is the air pump, that sound goes away after a min or two and the ticking sound is coming from the SSV valve, it is becoming loose but still works great, car drives like a champ still 10 years later with almost all original parts with 180,000 km

[@JustCallMeHorse]

I just pulled the end off then jubilee clipped it back together... No more fiddling around with plastic clips :)

[@angiemaisamuel9822]

what if you won't be able to release the fuel pressure line due to the car been starting up and couple seconds later die how do I go about?

[@tousshong9438]

It's too late now since it's has been a year after you asked the question but you could release the fuel pressure by open the gas cap. If that helps?

[@Shadow0fd3ath24]

@@tousshong9438 that doesnt release any furl pressure lmao. The pressure is in the lines not the tank. The gas cap is already vented so no pressure could EVER build up in the tank.

correct, fuel filter sock is built into the bottom of fuel pump housing

No. That is a pre filter sock. There is another filter downstream under the car

[@bluspectre2042]

It's designed to prevent hampering performance no matter the fuel lever, not for optimal gravity feed and access. Generally you want to drain your fuel to below half before working on any fuel system.

[@masterplasterblaster]

so, you just have to manufacture your own tools out of metal.. what the f****
