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

Sorry for video length, but I am trying to convey the story clear and concise.

I originally purchased the Aeromotive 13129 but have not been happy with the way it's been acting. I have since purchased the PQY unit to do some testing with. i paid for this regulator out of pocket. No free stuff here. I have about 50 miles on the new regulator and my original complaint has not resurfaced so far. I will report back if it does.

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.

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

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.

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.

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.

Has Mrs. Black ever come out to the garage and said to you;
"What is it EXACTLY that you do out here ALL day?"

[tsiawdspyder]

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.

Are u still running that ghost cam on the LSA 408…….im at the point where i need to get a cam and im just trying to figure out which route to go…..im at 9.8/10:1 compression with a 3.42 posi and 3000 stall built 4l65e…..the current 370 is 11.15:1 with a 220/230-.558”/.558”-117+4* cam and with the stall and gears with 2.45 pulley it works great and is very streetable and works with my vacuum brake booster…..id like the same with my 408 but i know the 220/230 cam would be like a stock cam in that big of a motor…….do you think a 114 Lobe seperation angle cam would be to narrow with our LSA blowers……should i just run with the ghost cam?? Do they make something a hair more aggressive…..if i recall you said you made around 650 whp with that cam right???…..i havent started to tear down the car yet so i have time to decide on which dierection i wanna go with the cam seeing as how my 15yr old son just recently talked me and my wife into getting him a ‘67 mustang coupe 289”…….were dailing it all in for him and im adding an efi kit for him (aces efi)…and at the same time we picked up a late model (‘96) 302 roller motor for us to build up together for when he graduates from that tired 200hp 289….. we got new forged flat tops and 58cc chamber aluminum heads to bring that anemic 8.5:1 cr to around 10.0:1 and hopefully over or close to 300whp (which is more than enough for a teenage boy in a 2800lb car thats over 55 yrs old)……ultimately id love to LS swap it but id have to fabricate some type of exhaust manifolds or headers along with the motor mounts…..so we just said fuck it and we’ll give the ford 302 a try considering its a dierect bolt in and all the misc. 289 parts will swap right over to the 302, including the ACES efi kit…..the efi kit even comes with a 3 bar map sensor….so if he is redponsible and does well and doesnt get any speeding tickets …….maybe, just maybe when he turns 21 we will bolt on a turbo kit…..that is unless theyve came out with a direct bolt in LS swap kit first……im just learning this ford stuff and its literally ass backwards too me😂😂😂……but between me, google, and youtube we’ll figure it out ……with the help of my paypal mastercard of course😂😂😂

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!

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

[carlosfley]

Over 2 years later, how is this regulator running?

[brianpeadenjr]

Thanks for the video! They are getting damn good at the cloning

[Luke-jwzn]

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

[jess]

Still all good? For the most part everyone seems pretty happy with this fpr. Was worried at that price but think I'm gonna get one. Last piece of plumbing my fuel sytem

[shinedowncannel]

11:00 probably wouldn't hurt trimming back those fittings a bit for a little less restriction.

[woog]

I scanned your channel quick but couldn't find an update video. Are you still happy with this regulator?

[rickroberts]

Do you recommend taking the pqy apart right out the box? Or can it be just slapped in? Did you ever test the fittings that came with the regulator?

[seemaab]

Great video! Quick question, what is the min and max pressure this PQY regulator can be adjusted to? Thanks from the UK!

[MotorSwapDan]

Ive got DW regulator for my MR2 wonder how it holds up

Rooting for PFi, Boostedboiz, or Garrett :)
