What size do you have now?

completely stock. idk was size stock is

Stock is something like 90 LPH. Dude, just get a 255 LPH, they are all about the same price so you might as well get the largest. Getting the largest doesn't mean you are going to drown your engine either, it just means the pump has the CAPACITY to flow that much so its not like you need to match the pump size with your combo. This is one of the rare cases where bigger is better.

Yeah, I would agree with a 255 as well.
