Stock pumps (not the high volume Cater mechanical) were made for the everyday cruising low horse engines. BTW the laying over IS what no adequate fuel feels like. Just splice the red pump into the line at the tank with short pieces of rubber hose, ad a switch up front to turn it on before staging (mech pump will still draw fuel through it for normal driving) Those red pumps put out a steady 5 pounds of pressure but still leave mechanical pump hooked up normally. Later on upgrade to the big stuff, pump, line and regulator, you’ll really need it for the 100 shot.
