In the PVC by the pump is fine for a guage just T it in , get a 0-15 psi gly-filled (liquid guage) perhaps Graingers.Be sure to vent the guage for an accurate reading as there will be instructions on the guage on this simple (but overlooked) procedure, There are some vented guages on the market but they are not as popular as the unvented style to date.1/2 inch tube is fine and 8 ft depth is fine also.Be sure your stone has a check valve on it as linears really struggle to push water out of a line at any depth.Brady makes a standard poly check valve available at any Lowes type stores (about $7)
