I did an Aerator pump conversion on my 08 Supra...it was a great improvement over the stock one rule pump. However, if I had to do it again I would go impeller driven. Much simpler install, will drain the bags pancake thin because they will pull there own prime. It will cost a little more but in the end I think you would be more satisfied with impeller pumps. With Aerator pumps you will have to use two pumps for each bag (drain and fill), vented loops, check valves, etc.. with impeller pumps its a simple ball valve, 1" line, they will drain and fill from one line. The Aerator pumps occasionally will also not prime, especially if you are
running multiple pumps off a manifold and not individual thru hulls.
If wired properly you can run multiple impeller pumps at one time with no issues.
Just my .02 after using both....
