Thx Chris - will have to research that…
Hopefully it’s OK to continue posting in this thread as a go through the truck mod. Happy to post in another thread, if that is more appropriate. BTW the vids are an excellent complement to the book. Thx Wayne… curious why the original air intake is blocked off & 2 new air inlets installed. Perhaps 2 circular dampers are easier than a single rectangular one?

Hello Phrang.
I use 2 two inch pipes from the gasifier filter to the motor compartment . I find it works best for me to plug and bypass the original air inlet and make two smaller inlets .

Thanks Wayne! Not sure if we’re dealing with excessive vapor pressure, so Sch 40 OK? Or maybe even Sch 20?

I’d stick with sch40, sch20 might burst if you have a backfire event.

That makes sense - thanks Cody.
BTW are backfire events common with ICE gasifiers?

Backfiring is usually only caused by an air leak, it’s not common on a well functioning system. If you floor the pedal, I have experienced a little puffback but that was more on the gasifier end than the intake manifold end.

Thanks again Cody…
So Wayne, the air cleaner assembly inlets… is their alignment/spacing significant for performance? ie. optimal air/fuel mixing? I am trying to emulate your pattern - just curious if there’s a rhyme/reason to it.
PS - I just want to thank you & everyone here for all their advice & willingness to share their experiences. It means a lot to me to be to be able to respectfully “stand on the shoulders of giants” - thank you all

Hello Phrang
No real rhyme or reason but trying to route the plumbing lines in the path of least resistance . There is not enough room to plumb into the air filter from the bottom or the lid so the sides remain for the plumbing connections . The sides of the air breather housing are just over 2 inches and the pipe or tubing that is welded to the housing has to be 2 inches or less in order to get a good weld. So in short I use the largest tube that can be attached easily.
By using 2 inch pipes , PVC and rubber couplings they all make good tight connections that can be disassembled easily .
There may be some merit to proper spacing of the inlet to aid with better gas and air mixing but I can’t prove it

Thank you sir! I kinda figured there might be physical constraints associated with the configuration.
BTW I came across specialized 2" PVC intended for “gas venting”, like for an LPG furnace exhaust.
IPEX System 636 Flue Gas Vent 2 inch x 10 feet PVC Pipe Schedule 40
As an aside, are there occasional/regular “meet-ups” or gatherings for us gasifier folk? It would be kinda cool if there was something for us like there is for Harley’s in Sturgess. In my neck of the woods we have weekly “classic car” meetups in the summer. Am gunning for that this year

I think I am using the same PVC pipe as you showed but at about half the price

Each year we have a gathering . Next up is Whitley City KY in October .
Below are some pics and videos from 2019.

Thanks Wayne, on both counts…
Lastly (for today) what models/years of Dodge trucks used the carburetted V10 engine? The RAM 2500/3500 starting 1994?

Hello Phrang
I think the dodge ram v-10 started in 94 and went until 2003 but none of them were carbureted to my knowledge .

Did you not convert a V10? If so, which one. Found Chevy had an R/V 10 series in the late 1980s
BTW is ABS OK to use for woodgas plumbing? Or do you recommend against it. In my neck of the woods it’s cheaper than PVC(gas)…

Hello Phrang
You were asking about the v-10 carburated dodges . As far as I know all the v-10 dodges were mutiport fuel injected and made from 94 until 2003 . I have gasified a 1995 and a 96 and have a 94 not gasified ( parts if needed )
I try to avoid gasifing any carburated motor if there is a multi port option .

I have never used the ABS piping so can’t comment on it .

Thanks Wayne… I’m slowly realizing there’s a lot about trucks I still need to learn, incl MPFI. So I will be on the lookout for my NEXT gasifier project: V10-MPFI. What make/model/year fits that bill the best? In the mean-time, I shall continue with the Dakota. I’m modifying the air cleaner now. What air filters do you recommend for the 2 air inlets? A dedicated filter for each? Mounted where? I intend to swap out the stock air cleaner first in order to get the truck running on 2 dedicated inlets, before installing the 2 woodgas inlets. And then complete the plumbing… pics forthcoming

I made a couple videos of the above details you were asking about but having trouble loading up to youtube . I may have to wait until my Son can help.

Hi, Phranq
I’ve only gasified one vehicle so far. A 1994 Dodge Dakota. On that project I did use ABS for all the plumbing. Because like you it was a lot cheaper where I am. Also it has a higher resistance to cold and possibly heat too though I’m not sure about that part. So far I haven’t had any issues with it. Even with one pipe two inches from the one exhaust manifold.
I would recommend using the ABS for plumbing especially if you can get it cheaper.
P.S.(The good thing is that it’s already black and won’t need to be painted.)

Thank you Bronlin
Since this is my 1st conversion, I will go with ABS until I discover otherwise. BTW max temp for PVC is 140 F, ABS 176 F & cPVC 210 F.
Wayne thx for the vids… was thinking the same - nice to get confirmation
