Amazon PQY Fuel Pressure Regulator VS Aeromotive 13129 comparison you make the call.

[@Dynodon64]

When hooking up the vacuum line, it is suppose to drop the pressure. It is compensating for the vacuum in the intake. When you have vacuum in the intake and the injector fires, the vacuum sucks more fuel through the injector,. So the drop helps maintain the delta across the injectors. Just when you go into boost, it raises pressure to offset the boost pressure in the intake. Works both ways.

[@PNW_Car_Mods]

100% correct sir!

[@BadLuckGarage]

I've never used the PQY regulators, but I've used several other China ebay regulators and always had good luck with them.

[@PNW_Car_Mods]

I can't remember for 100% certain but I think it may have been on of your videos I was watching that gave me the thought to make this video lol. So far the china regulator is outperforming the expensive regulator in function. Thanks for stopping in sir. :)

[@BadLuckGarage]

@@PNW_Car_Mods Honestly I’ve had higher failure rates with Aeromotive than I have with the China knockoffs. Which is sad really. I think I actually mentioned it in one of my videos but the last Aeromotive regulator I bought was probably 10 years ago and it lasted less than 6 months before the diaphragm got a small crack and started causing erratic pressure issues. In their defense Aeromotive actually sent me a new diaphragm free. But I decided to try a $35 China knockoff after that and that regulator lasted me for several years with no issues, then was sold with the truck and to my knowledge is still functioning today. Since then all I’ve used on my builds is the China knockoffs. The one I currently have on Chaos Theory is an exact knockoff of the Aeromotive 13301 but was like $25. It’s the first time I’ve used that design and it’s a lot smaller than the ones I generally use so I just wanted to try it out. So far I think it’s doing ok but we’ll see.

[@marshall8490]

I like that fuel psi gauge where did you get it from?

[@TheAkstewie]

I used a PQY regulator until I needed bigger I/O at 10an. They work 100% just as good as a top dollar Holley or Aeromotive. I never had any issues at 60psi of base pressure up to 74psi with the boost ref hooked up.

[@PNW_Car_Mods]

Good to hear. I'm still having no problems with them. I am currently running an 8AN PQY and working perfectly. Put the 6an PQY on my ls swapped Ranger and it lives on there.

[@BOOT]

11:00 the fittings look too deep into the Aeromotive regulator, metal center of diaphragm may been hitting them. PQY reg fittings seems shorter. Also in the base, the center post/seat could be diff heights, looks maybe deeper/shorter on the Aeromotive. Normally they are top line but anyplace can have a bad run of parts.

[@PNW_Car_Mods]

Ended up going to an all 8an PQY Regulator and lines from the 6an stuff that was in this video.

[@Labergemusic]

[@PNW_Car_Mods]

@@Labergemusic Where?

[@Labergemusic]

@@PNW_Car_Mods I might not see them in this clip, but the 6 ORB fittings the Aeromotive uses needs an o ring between the thread and fitting

[@PNW_Car_Mods]

@@Labergemusic oh I think what you were seeing is just the second set of fittings sitting there. I swapped the used fittings over from the Aeromotive to the PQY and reused the o-rings. So the fittings you see sitting there are new and we didn't use them.

[@Spyder_tsi]

I recently bought the exact same one on Amazon and it was junk/faulty so sent it back. Would not regulate below 90psi some reason. Hooked up correctly but wouldn't drop pressure. Vacuum on or off was 90psi with screw all the way backed out. Ended up buying an AEM.

[@PNW_Car_Mods]

That's a bummer Justin. So far mine is still going strong and absolutely works better than my Aeromotive did. That being said I don't hold it on a high pedestal either. It is cheap chi na parts. AEMs are good units and a lot of people use the Holley regulators as well.

Bring one feed line up into y and split off to each rail. And in the front use the regulator as the crossover, for lack of better words. That should fix that fuel pressure problem

I have completely revised this deal since then. It is now a full loop an 8an regulator at the very end of the line and then returns to the tank. In other words it is no longer a stubby deadhead setup.

[@PNW_Car_Mods]

Good luck with it! Still running 2 of these on a couple of my cars.

[@WhereistheVINnumber]

Thanks for making this video. Your car looks immaculate. :) I was watching the entire video but it didn't address my "problem". How long does your regulator hold the pressure? Mine drops from 58psi to 43psi as soon as I shut the engine. Then it climbs down very slowly (15mins) to about 14 psi. In 1 hour it shows zero. Watching the video I can see that your regulator acts the similar way. So is this a problem or not? Many say that regulators should hold the pressure for about a day before the pressure starts to drop. Is that true with these regulators or that statement applies to stock regulators only? I just want to find out if this pressure drop is totally normal or a faulty regulator.

[@PNW_Car_Mods]

Mine drops fairly quickly most of the time. Some days it will hold half for like an hour but most of the time it drops to half within in a minute or two and drops to zero within a couple hours. I have never seen a non factory system hold pressure myself. That being said the simple answer is, does your engine start as it should? If yes, then don't worry about it.

[@Luke-jw6zn]

its the gauge, You need a gauge that vents to the atmosphere. aeromotive addresses this.

[@PNW_Car_Mods]

Using an autometer pro comp mechanical. There is an absolute difference between the two brands. The PQY flat out worked better IMO.

[@desert_edition_na6]

Just got mine and the body is also drilled and tapped off center. Gotta wonder if these are aeromotives that didn’t pass QC. Rock on!

[@PNW_Car_Mods]

I'm not sure but I will say that so far the PQY out performs the aero just in much smoother operation by watching my fuel pressure gauge. I'm keeping the cheap one on the car.

[@lukasethan6429]

Just for my experience in aircraft engineering in management for a large company usually there off-center so when they put them in the fixture, they only go one way. I’m almost certain it’s off center for a reason like that. I could be wrong just my two. Cents.

Now I just wish they would make a plus sized ghost cam lol.

Definitely not normal. Something is leaking internally. Could be leaking injectors, or the check valve internal to the pump or tank. If it doesn't want to run at all it could be the regulator failed. Usually they will leak out the top half of the regulator if that happens though.
