Can I use the “better 2011” hydroboost?

[treehan77]

Can I use the 1781036 hydroboost unit (2011 MY only 2500HD)? Supposedly this is a better unit than the others. I have seen many use it on there gmt800 Duramaxes, just wondering if anyone has done it on a Tahoe or Yukon? Sounds like you’d just have to enlarge the hole to fit. My truck (05 Yukon) already has hydroboost, but it is leaking AGAIN. Replaced it a couple years ago, I hear this is is better.

Curious who says it's better - I've had 4 hydro boost gmt800s and never had an issue. Highest mileage is 270k and gaining. Sounds more like low quality reman units which is unfortunately. Quite common for anything reman at this point.

I had 2 reman units leak from autozone, after the second one, I gave up and purchased a OEM unit and has not leaked in 3 years.

Hydroboost upgrade for lly

I have done endless research and i find that most that upgrade to the lml hydroboost replace with either part number 19371361 or 178-1036. However when I look up to search the part number I come across two websites(one happens to be a vendor if I'm not mistaken) and they state part number...

Did you end up trying out the 2011 Hydroboost?

Nope, nobody seemed to know anything about this, I haven’t ordered a replacement yet, still leaking slowly lol
