I did a little research and a healthy 2.7TD makes 11.5psi of boost, that's a lot to overcome and trying do so will you quickly show just how many leaks you have in your system. Madscientist, in an overabundance of caution told you not to run HHO through the intercooler- this was said because KOH and NaOh will both attack aluminum, the favorite material for intercoolers.
That being said, you're most likely going to have to do it anyway, and here is how: dry your HHO.
Cut two 10" sections of 2" PVC, on one of them, glue caps to both ends then drill and tap one end center for a barbed hose fitting, on center of other end drill and tap for same. Screw in both hose barb fittings with sealant and set aside.
Obtain 2 Oatey 2" plastic mechanical test plugs, product #33401 and (1) 2" PVC repair coupler.
Cut the coupler in half so you have two rings and glue one ring on each end of the second 10" PVC tube so that the ends are flush.
Measure test plug depth so you can determine clearance distance for drilling side of tube at each end for barbed hose fittings. Extra layer thickness from split coupler is to prevent tube diameter increase from test plug tightening.
Cut four 2-1/8" dia. discs of SS, brass or bronze screen, NO aluminum or fiberglass or plastic.
Push one disc into tube a little beyond hose fitting hole, turn over and pour in 1 cup of uncooked rice, any brand.
Push a screen disc down almost onto the rice. Push in another screen disc leaving 4 or 5 inches between it and the last one. Pour in 1 cup of uncooked rice, any brand.
Push in last screen disc.
Install fittings with sealant and tighten test plugs.
You now have an inexpensive HHO dryer.
On installation you will run the line from your bubbler to the bottom of the first simple tube to catch gross liquids, line out from its top goes to bottom of gas (rice) dryer, line out of dryer's top intake air cleaner.
Both tubes need to be installed vertically.
Madscientist got turned around and accidentally said "advance" pump timing- he meant "retard" pump timing because an HHO enhanced combustion flame front moves so much faster that it advances your diesels timing for you! Therefore you need to retard the pump timing, starting with 1° while evaluating performance. If it is possible to decrease the fuel delivery curve (couldn't find your injector pump model) then gradually start doing that, also while monitoring performance. Timing, fuel volume and HHO volume must be tuned to obtain the best results. Need to know your year model also.
