Identify Hydroboost

[Dvldog8793]

Howdy
Vehicle is a 1998 suburban 1500 with 6.5.
How do I determine what hydroboost unit to order?
I know from my CUCV experience that there are a couple different ones, but can't seem to find a good way to ID it by ordering it.
The RPO just tells me that it is a hydroboost system and not what one???

I've tried the search function and no real answer....

Thanks!!!

Check the actual RPO code.

If it is JD5 or JD6 the AC Delco reman number is 14PB4045

If it is JD7 the AC Delco reman number is 14PB4047

The reman cost is $229 for the first and $240 for the second, including the core charge of $27. This is straight from the RockAuto website.

Hope this helps.
