I think a single 14mm would be a better daily driver option than any dual pump setup as keeping things simple always seems the best in the long run.

[@Balakay9435]

Hell Yeah Brother 🇺🇸🦅

[@73cjproject]

Awesome content and information! Thanks again for sharing the knowledge. That definitely helps answer a bunch of questions and give insight of what direction to go! Would you ever run triple 14 mms?

[@horsetorquesdiesel]

if you needed more than 3600hp worth of fuel yes!

[@rtz549]

Look into drilling that pressure sensor and safety wire it like they do on aircraft.

[@torysukut9692]

Do you think DDP is working on making a 14mm pump? Great content as always brother. Very informative

[@horsetorquesdiesel]

I havent asked in awhile but was told not yet!

[@DIGGINGITDEEPER]

we are currently installing exergy 12mm pump on a late 5.9 curious as to what fuel line modification is going to be like. great content man thanks for the info.

[@horsetorquesdiesel]

They definitely have better throttle response

[@slowaf12v]

Great explanation video josh!

[@horsetorquesdiesel]

[@b2hibry]

CP3 have come a long way for sure! You mentioned mixing pump sizes and one thing I've discovered is... DON'T! Unless you can live with an annoying surge. And on the leaking rail pressure sensor, it's a manufacturing tolerance issue. Believe it or not, they are supposed to be a one-time torque item. I didn't know that until I chased my ass for months on a leak.

[@horsetorquesdiesel]

an impact on a crows foot makes up for the tolerance lol! But good to know!

[@b2hibry]

[@michaeltrue1143]

I run the Industrial Injection 12 mm in my truck no complaints here..

[@4wdiesels]

Josh, any advice for quieting down the gear lash noise from an S&S CP3 conversion for a '19? I did the no tune pump and it's noisy as hell. I just pulled it out the other day and phased it to engine TDC and double checked bolt torque values but it's still clattering under light loads and when letting off the throttle. S&S says it ain't causing harm and the truck does run great, it's just annoying and borderline embarrassing. Thanks again for another informative video. 👍

[@horsetorquesdiesel]

clock it 180* out from TDC

[@ChaosViper67]

Would a fleece powerflo be okay for dual stock s&s supersport cp3's with 200% and really conservative tuning? It's what I have with my VP truck that I am going to convert to 6.7CR. Idle sits ~16-16.5, 15 cruise, and no less than 14 no matter how long I stand on it with Quadzilla Adrenaline V2 maxed out tuning. I'm going to go to a 6.7CR with garrett compounds G42 73/91-82/75 1.01 T4 with steed speed T4 turbosmart 45mm high psi gating into G55 106/144-112/106 1.24 v-band inlet. I'm going for the most hp I can as clean as possible. Fully built girlded small cam milled intake shelf with stock replacement shelf. Or do you think I shoukd go with 250-300% injectors and have even shorter duration?

Need some help with my cp3 r70! I mounted a cp3 pump on my vw 2.0 and i cant figure it out how to calibrate the metering valve … Builds too much pressure at idle and the car shuts off. Any ideas on how i can solve this problem?

[@dillanmarcos]

Thoughts on a single 12mm vs 2 stock or “sportsman” type pumps sorry if I missed it in the video.

[@horsetorquesdiesel]

Single is always better in my opinion less, moving parts, less failures!

[@BentonL]

I called DDP about remanufacturing my pumps and what options I have. I was told they dont make pumps. They have an outside vender with their branding. Since many "new" pumps have cores, I was hoping they could resize my pumps. I have been googling this topic in many ways, but I am coming back dry. Please shed some light on this topic and shops who resize or reman pumps.

[@curtisd8206]

Buy whatever size pumps you are after from your preferred company and use you old ones as cores. Just way way simpler

[@horsetorquesdiesel]

just buy new, its not worth it.

[@ahmedalial-saeed9471]

I have RAM 2022 eco diesel with CP4 , it’s recommended to replace it with CP3 or it’s not possible?

[@wheyez1]

With the increased flow of the CP3, do you increase the line size from the tank? I have noticed a difference in performance from the airdog, drawing from the top of the tank as the tank level lowers. I can only imagine if I increased output it would be even worse.

[@3DProductions]

airdogs and fass pumps come with 1/2" fuel line

[@powers9328]

Your issue is the draw straw. If the factory sump cup is damaged or the straw that happens more commonly known as the 'quarter tank issue'. You can either take it apart and insure its all good or drill a hole in the bottom of the tank and install a sump.

[@grant_6.7_5th_gen]

Josh with the 6.7L Cummins Dual Pump Kit Junction Block with Rail Sensor Port do you have to make your own lines from the cp3 and block to the rail?

[@horsetorquesdiesel]

only line you have to make is from the block to the 2nd pump.

[@TAC_Gray_Beard]

@@horsetorquesdiesel For a 850-900 hp tow rig build with compounds would you do a single or dual cp3 setup?

Josh, Do you still have a 12mil cp3 you’re looking to get rid of? Where can I DM you?

[@ChannelZeroOne]

I would like to know how to rebuild these and where to get the parts.

[@horsetorquesdiesel]

it requires a test stand cheapest one i have seen is 15k new.

Can greater then 14 be built?

[@Barrage_S197]

What would you recommend running for say 1000whp? 12mm vs 2 10mm or stock and 10mm if it could support that power

[@3DProductions]

get a 12mm use stock for core charge or sell it

[@horsetorquesdiesel]

12mm

07 5.9 hard start after warm. Like 30 seconds crank plus. LOWWWW FRP while cranking. Motor cold fires right up. Pour water on hot cp3 it’ll fire right up. Brand new 30% injectors and tubes brand new fca brand new lift pump in tank brand new fuel pressure sensor. Any ideas? Hard start while warm or “hot” but fires up cold all day. Runs like a champ when it’s on also.

[@horsetorquesdiesel]

First thing I’d check is lift pump pressure, then connecting tube torque, then I’d check the relief valve

[@damonsmith8411]

@@horsetorquesdiesel I just had the lift pump installed professionally so I would “assume” it’s correct. I just ordered a brand new relief valve today and will put that in tonight. I have all tubes torqued at 37 ftlbs. I’ll Venmo you 100 if you help me solve this problem

[@nsacco208]

06 g56 truck, idle is great while warming up, after warm up it will sometimes go up and down as does rail pressure. Do you think it's the pressure thing on the cp3? Stock truck

[@nsacco208]

Almost what you'd call a slight surge

[@horsetorquesdiesel]

is battery voltage changing?

[@nsacco208]

No, battery voltage is constant. Just rpms and rail pressure

[@cole1407]

Well crap I have the PPE kit, hopefully I can buy a kit to get a true dual feed setup
