Yes, return to tank.
What did you use for the flex fuel line?
ordered new emissions equipment. $333. A good chunk of that is in new o2 sensors. Hoping the purge valve coming with new intake isn't broken, otherwise, another $25. I haven't ordered the cats yet, but going with Walker's CalCat - supposedly a better cat and definitely a better warranty (5 yr/50k mi) - so that will be another $300. Walker 81724 is the part number if anyone cares.
I'm a little disappointed in Dakota Digital gauges. I ordered on 6/22/16 and just got an email it won't ship until the 19th of Aug. Which is fine, but this is the 2nd time they've updated the shipping date. I did order through summit, so I am going to complain and hopefully get a little knocked off the cats....?
