Hello Garrett! I just did this on my 109, per your instructions, and it worked AMAZING! Truck was very lethargic before. I also installed a boost and egt gauge. WAY better power now, and I'm hitting about 1150 degrees now and roughly 8-11 lbs boost at basically WOT, in 5th gear, 40mph, with 1000 gallons of water in the bed. I use this truck to haul water to my house, and I greatly appreciate your help! 750 degrees cruising around town.
I know some of your videos are a little old, like this one, but dang they're helpful for us new guys. Thank you for taking the time to make 'em and please, please, please don't ever let 'em disappear! Thank you.
You bypass it because it is a failure prone component that can't be repaired or improved, and isn't necessary for engine function or multifuel capability. The original purpose was to meter fuel based on density to maintain a consistent power output from the engine regardless of what fuel was used.
A few questions on that air line, is it nylon with Teflon lining? Or just nylon? what’s it’s burst pressure? And what else could be used as a substitute? Thanks in advance!
Yes it is Teflon lined nylon D.O.T air line. Not sure what the burst pressure is, but I know its well over 120 psi. You can also use nylon line without teflon lining, but gasoline isn't friendly with it. I'm not aware of any other good substitute. This line is available anywhere semi truck parts are sold.
I checked mine today, and i believe it is already bypassed. I will make sure tomorrow it has been done. Are there different styles of these? Mine is flat on the top with 4 bolts versus the one in your video is alot taller with 3 bolts on top. Thanks for the help

Did you tell me a shorter version of this? I don't remember it being that much involved in this area, i thought it was mostly on the exhaust side.
No, that was flame heater delete.
Why would you bypass the FDC, what is it's purpose?.
You bypass it because it is a failure prone component that can't be repaired or improved, and isn't necessary for engine function or multifuel capability.
The original purpose was to meter fuel based on density to maintain a consistent power output from the engine regardless of what fuel was used.
Hi Garrett, why are you taking out the fdc? Won't diesel be the only fuel you can use if you do that?
No. The FDC is not required for multifuel capability and is a high failure item.

any power gains by doing this mod?
Thanks
Sometimes, but it's not consistent.
What is the purpose of these procedure?
It's another point where fuel leaks into the engine oil inside the pump.
@@tacticalrepair it doesnt affect the performance even though im using my truck carrying heavy loads?
@@markpelagio690 it can give you more power, yes.
What symptoms are created when the fdc fails or begins to fail? Thanks
Fuel in oil contamination. Very serious problem.
Ok thanks, so it really doesn't create symptoms till its too late. I will have to keep an eye on my oil till I do this to mine.
@@scottbrutus you need to just do the bypass. No reason to leave it hooked up. Under $10 in parts to complete the task.

Yes that is a G code pump. No compensator to bypass.
