12v Cummins Chinese made P7100 P-Pump Replica - Let's disassmble and compare to Bosch

After searching for information or reviews on one of these Chinese replica injection pumps and coming up with nothing I decided to do it myself. Bosch is no longer producing these pumps new so it's becoming more difficult to find one in good condition. You can buy a used one and send it out for rebuild but the cost is upwards of $3000 and the wait time and still have some parts inside that are being reused. I opted to try this out for around $1000 knowing that there is a risk of potential failure as with anything.
I decided to install 191 delivery valves and 4k governor springs while I had it apart. This video shows what I found inside and shows the different parts and some detail on disassembly.
Please if this video was helpful to you then let me know in the comments. It's always a treat to get a notification that someone watched and commented, even if you just want to tell us about your project I love to hear it.

The difference with the do is the thickness of the shoulder above the fuel cuts. The 131s have a thick shoulder and the 191s have a little bit narrower shoulder resulting in how much fuel flows the the do. Hope that helps!! 🤘🏽

Thanks for taking the time to do this video. I suspect you can use your dial indicator tool to measure maximum lift on the pump and compare that number to determine if this is a 160, 180 or 215 clone. That would be awesome information. Please add follow up videos as the months roll by to let us know how it is performing / working. Thanks!

Good review. I've been looking for feedback on these and yours is the first I found. I'd be genuinely curious to know how the hardness of the wear areas, like the camshaft and lifters inside the pump, compare to the Bosch originals. This would seem to be the main area where longevity could become a factor. Thanks for taking the time to go through this for everyone.

Bosch still makes the p7100 under mico brand in india. these 12 valve engines are still in production for off highway , marine & generetor application. New mico branded p7100 is around 700$ here.. they were made for on highway till 2011 and millions are on road because these engines are immortal.

Do not cut foot on afc , the stock one ones are no longer available, buy a power driven diesel foot that is already cut and if you do not like the results you can put stock one back in. You will never be able to get rid of idle haze wants cut

@MrDylman55 9 ай бұрын
​@BrandonWicknick the afc foot cutting just gives you more rack travel. More rack travel means the plunger started riding on the cam earlier and comes off later, effectively giving you a longer Injecrion event and more fuel.

You want to cut or remove .100-.120” off the barrel of the arm. This is the part that touches the inside of the AFC housing. And limits rack travel. You do not want to cut the foot. The foot helps control low boost fueling.

Thanks for the review, and please follow up, or even get second opinions. A while back, I figured that someone had surely made a cheap clone by this point, or even a decent quality variant that doesn't cost over $2K. Then I saw these and have been wondering ever since, if they're ever going to be a better option for diesel hotrodders and pullers, over a 30 year old pump. They are becoming harder to find as time goes on, and core charges are expensive. I hate chinesium as much as the next guy, but if one of these can do the job well, maybe with a little 🇺🇸 or 🇨🇦 parts injection, that would really help a lot of people out.

Where is your AFC housing plumbed in for boost pressure on your 24v Cummins? I set my truck up. But for some reason it seems like it falls on its face after I hit the turbo, almost like it is out of fuel. I drilled a hole in my neck above the heater grid and plumbed it in there. But I am not sure where exactly it is supposed to go. I also just bought some 191 delivery valves for it as well. And have installed the 4k springs in the pump. Any help would be much appreciated. Thanks in advance.

Still watching your video but the differences on the DV’s. The flute volume and shoulder hight. Lol it’s wild that they send that with what essentially looks like a full cut. The stem I agree is for the spring, normally the stem is for a constant volume or pressure setup (I’d have to check my book for which) but it’s missing the rest of the valve system in the holder for that. The holder also looks like a strait shot .120 holder not the valved oem holder which is again wild lol. Depending on the cam if you benched that thing with full rack it should really displace a lot of fuel but have extremely poor control over start of injection and end of injection. Switching out to a shouldered dv is definitely going in the right direction :) awesome video.

I used to work for an oilfield company that would contract parts out to a Chinese Manufacturer . The Chinese would make parts to our spec , we would QC the parts ; 98% of them would pass , Hardness and metallurgy was the same as what US machined parts were.

So where do you go about getting a Chinese p7100? Temu? Lol Im planning a p pump swap for my ‘02 24v HO 6 speed. Its about to hit 100k miles and close to ‘broken in’ heh. Got the crazy carls kit and been piecing together a lot of stuff over the years for the time. I knew i wanted to p pump it 8 years ago when i bought from the org owner with 79,000 miles. But i told myself i wouldn’t tear into the motor and do anything to it till it had at least 100k on it first. Took 7-8 years to out 20k on it. Is the Chinese pump worth it? From what i gathered from your over view im more curious now and want more i for. I mean…its just a pump. Bosch is german, and germans do make nice quality mechanical things. But so do the Chinese, and they do it cheaper than the germans lol. Im not against getting one of these to build. Id defiantly would go thru it like you did and make it the way you want. More vids, install of it and test drives!!

The delivery valve cuts are how it gets more fuel. Full cut allow to most fuel inside that cylinders plunger bore, the more you cut steel away the more fuel can makeup the space the bore can collect.
