I hate noisy elec pumps & have 2 of these Mallory gerotor style pumps. One on my 71 W100 with a pumped up 383 Magnum with an Eddy 800 Thunder & the other on my 68 D100 with a 383 magnum & Eddy 650 AVS. They're super quiet & you can barely hear them running. These are set to 7psi & that's what my regulators are also set at. Mallory makes 70, 110 & 140 gph versions. 110 would be fine for your application. Summit has them for $234.
