According to what I've read, the Alphacool Lucite upper housing does not have a larger diameter inlet. The center threaded and plugged port is intended to be used for filling and bleeding air, though I imagine it could be used for a 3/8 OD inlet minus the 90 degree bend?
Some third party could produce a larger inlet upper housing for these pumps on a limited production basis on a CnC machine, but would there be enough economy of scale to keep the price under the cost of the whole pump? Would enough people pay 125-150 USD for this pump with a modified housing to justify the work?
Cheers,
Joe
