Thanks for sharing, now I know what to expect :thumbsup:
This bluing starts about where my thumb is. I probably should have had a shorter rod according to the instructions, but hey, I do my own thing.
Ok, so no PEX tubes then, perhaps also use O-rings that which can take a beating or two.
I just remembered another change I did. The red PEX tube leading from the muffler side of the reactor to the blue bubbler ended up melting. I replaced it with some flexible copper tubing. I think I used compression fittings.
Did you compare any fuel mileage the GEET way vs original?
