It is a vapor injected system. For more info check out my other posts.

Hi Friends, Ijust wanted to let you know that up here in Quebec we have had a very cold winter, especially mid-december to mid-january where overnight temperatures were below -30c almost every night. I used my truck a lot during this period clocking 6000KMs always keeping a 3/4 tank of gasoline expe...

The dealer wanted 1600$ for the cats. I ended buying a used one (25000km) for my local LKQ dismantler for 200$. After having it installed, i immediately noticed that my truck’s power had been restored. The check engine light hasn’t gone on and yesterday I did a round trip to quebec city which is abo...

Thanks for your insight, i’ll give that pressure test a try and I’ll let you know. Maybe i’ll use a cheap boost gauge.

Friends, I have a prinns system on a 2015 silverado 2500hd 6 liter vortec. Lately it has been getting very lousy fuel mileage and occasionally I get a p0420 code with the engine light on in the dashboard. Being the mechanical genius that I am, I erase the code and hope the problem disappears (just l...

Update after 115000km: I wanted to share with all of you my experiences with the Prinns system i have on my truck. In earlier posts I mentioned that my heads had to be re-done with new propane compatible valves and seats. I have not had any other proplems related to that since. One major proplem tha...

That is interesting. Apperently the NG prepped 6.0 motors are not availlable for pickup trucks but only on the commercial delivery panel trucks. Mine is a flex fuel motor (are they not all?) but i don't think that that automatically qualifies it as an LP or NG prepped motor. I got the truck back las...

I have had a cylinder go bad on my 6.0 chevy. At first I thought it was an ignition problem but after checking the cranking compression on all 8 cylinders, 7 were at 205-210 psi and cylinder # 3 was at 140-145 psi causing a misfire code p0303. Turns out I have a burnt valve and the cylinder head has...

Update after 6 months: I travelled over 40000 KMs since i got my truck converted in may. I have had no problems with the system thus far. I am still averaging about 25l/100 pulling my 5000lb trailer (30 foot gooseneck). The maximum consumption i have seen was 40l/100 but that was an extreme load (12...

At a steady speed of 100kph, the engine rpm is at 2250 with a loaded trailer which is in fifth gear with the transmission in trailering mode. With my trailer empty it sometimes gets into sixth gear when going slightly downhill or on a very flat stretch of highway and the RPMs go down to 1750. With t...

Close to 30l/100 may seem high but at 49 cents a liter it costs me less than 15$ to travel 100km pulling a 5000lb 26 foot trailer with loads averaging a couple thousand pounds. Sales tax not included. That is about what a duramax diesel might do if you are really easy with it. Plus with a 210l tank ...

Yes, the gas consumption averages out to 29.5l/100km compared to petrol 24.5l/100 for 14 fill ups. Again, gas consumption is calculated and petrol consumption is the number indicated on my dash board.

Update after 6 weeks: I travelled 8000 km since the conversion and i am so far quite happy with the system. Using the l/100km indicator on my dash board which tells me how much petrol i would have normally used, i was able to compare that to the actual l/100km of propane my truck consumed. From this...

Update: small problem today, the system alarm went off and the prins shut down. It immediately switched to petrol and i hauled all morning with the system off. After lunch i went to the installer's (it was on the way) and the diagnostic tab on his lap top program displayed an injector failure. He ch...

What is a flow rating of 82? What does it correspond to with regards to HP rating?
