In this video we show you how to remove your high pressure fuel pump to upgrade the internal components so that you can maintain high fuel pressure while turning up the boost on your Mazda Speed 3. We used autotech internals for this install. This job involves some crucial components of the engine so be sure to orientate your HPFP internal components correctly when installing the new components. Remember to pull your ignition fuse or fuel pump fuse then crank the engine to drain fuel pressure before disconnecting lines.

Screw everyone else this is the best installation guide on RU-vid for the install. Not one person mentioned what side the bottom piece with the hole should be facing/located !!! Except this guy. I had to do a lot of research and this is the only guy that mentioned that part !!!

@KalahProductions 2 месяца назад

One thing I appreciate you mentioning is the ticking sound from the upgraded internals! I remember when I first did mine and I heard the ticking, I thought something was seriously wrong!

Great video. Been working up the nerve to do this for years now and finally pulled the trigger today lol. Original owner of a 2008, and while my stock internals have been fine for the past couple of years with a shelf cobb stage1+sf tune, I am ready to go to the next stage and this bugger has been in my way long enough! Thanks guys

@willg125 3 года назад

What other aftermarket parts were you running with the stage 1+sf before HPFP upgrade? trying to figure out if this is what I need next or if I can hold off a little while longer.

@obomasinladen 2 года назад

you were running a cobb ots tune without upgrading your hpfp internals? Consider yourself very lucky you didn't zzb.

@obomasinladen 2 года назад

@@willg125 You need to asap if you introduce mods or a tune. The stock internals cannot handle pushing additional fuel through to match the increased airflow. If you don't do this you risk running lean and causing detonation = bye bye engine. Thats why so many speed3's are blown up and they have an "unreliable" reputation. People can tbe bothered to educate themselves before modding/tuning.

thanks guys, I was looking for a detail one on taking the high pressure fuel out of the car.

@mitchhart5521 2 месяца назад

I followed the steps and took out the rod and spring to get to the 18mm. I have no idea why 18mm or even 19mm isnt fitting. It just sits on top of the nut

@MZSP3MARIA 5 месяцев назад

Mine did not go in as easy, it’s like the coil is holding it back or something inside so I’d have to compress it but your video shows me that I do not have to force it in. Any ideas ?

@ferassaleh9180 3 года назад

I have mazda 6 2017 the hpfp doesn't work probably, where can I get the internal parts from?

@0riginalfuz 4 месяца назад

so i doubt ill get a reply but what kind of oil? just motor oil?

@Calvinm 4 месяца назад

Ya almost certain it was just motor oil.

Would it be safe running a bov Cobb intake and grimmspeed boost controller with hpfp? Asking bc a guy is selling me one and he bought it with these upgrades but unsure of hpfp

This is 2012 ms3

@proto4747 4 года назад

Nice video, but try and keep a rag to catch the fuel as it drops out of the old parts. Makes me nerovus lol

@thefz1rider 3 года назад

What brand of security Torx 25 did you use? The hole in my Craftsman's is not deep enough to allow the teeth to engage to get the low pressure connection off.

@bluesclue3667 3 года назад

u need a t25 with a hollow middle. ur local shop should have one for 10-20$

@RAWTEN 3 года назад

Whats your actual pressure at idle after driving for awhile? I did the corksport rebuild kit and autotech internals installation and the prime as well before starting it. And on a cold start it reads 420-430 consistently at idle but after driving for awhile it dips to mid to low 300s? I'm just confused if its suppose to fluctuate that much or not.

@jb6574 2 года назад

No..something is wrong. Never should drop below 400psi

@tyclemons1929 Год назад

Ever figure it out? Having same issues

@bobbydouglas16 3 года назад

Great video! Is there a way to verify that HPFP is installed by simply looking at the PSI readings you viewed after installation. I am buying one from a dealer and was told the previous owner did, but i want to make sure without pulling it

@Calvinm 3 года назад

Hey, no you can't really rely on the PSI readings because even the original HPFP can spike to 1800-1900PSI. If it's hitting 2100 PSI it would be a decent assumption that it's been upgraded but it would be best to do your due diligence and take it out and check. If you take it apart and you can pull the shaft out it is 100% original equipment. Best of luck!

@bobbydouglas16 3 года назад

@@Calvinm exactly what fuse needs to come out ?

@Calvinm 3 года назад

@@bobbydouglas16 I don't have the exact fuse number but in your fuse box in your engine bay you should be able to find a fuse labelled "F/PUMP" rated at 30amps. Pulling this will likely kill power to your low pressure fuel pump and enable you to drain the system by cranking the engine until it stalls.

@mzdamps 2 года назад

Do you need a tune after internals?

@motodave2338 3 года назад

I broke the yellow clip on the fuel line. Any advice on where to get a replacement clip? Or if there's an alternative way to secure the line? If I have to I'll order the whole line

@Calvinm 3 года назад

I'd try calling an auto wrecker to see if you can get the line or just the clip for cheap. Or maybe a ziptie can do the trick temporarily, best of luck!

@73roken Год назад

My god with the amount of stuff you removed, and having to drain the line, and all that other complicated stuff you did I’d rather pay a mechanic to do it on my Mazda 6 lol. At least now I know it’s out of my capabilities lol
