    Wound up buying the DSX aux pump and it is performing wonderfully. Took a bit of trial and error to get the pressure to act right but it is doing great...now trying to fix my lowside control but think I've got that sorted.
    I have added everything except port injection. Chose the DSX aux pump due to cost and simplicity.

    Anyone having any issues with their tank fitting leaking? Just checking before I pull the trigger on a dsx system

    Use the sealant they provide and don't go too deep when using the tap. I've removed my tank 5-6 times since installing and no leaks at all.

    I?ve seen videos and the people?s fittings are always loose as fuck, (I?m a plumber by profession) and that loose fitting shit doesn?t sit well with me, was your?s snug?

    Snug as a bug in a rug. Keep the NTP tap shallow so you get a good bite. No leaks from mine but if it does ever leak, I plan to get a bulkhead fitting but it's doing great so far and I've removed the tank at least 5 times since installing it this summer. This is the best pic I can get for now.

    Not certain about your tank but the tank in the Yukon was exceptionally thick.

    That?s what I like to hear, I have 23 Silverado and I?d imagine it probably has the same type of material as your?s.
