You can use any Auto Meter Full Sweep Electric Fuel Pressure gauge to monitor lift pump (not injector) pressure, though we recommend the 30psi units as a best fit for this application. However, you must also install a #3279 pressure snubber fitting and #3227 stainless hose kit to protect the sending unit as ’98 to ’02 (and some late ’97 or early ’03) Dodge Diesels produce a very sharp, very high pressure spike in excess of over 300psi between the lift pump and injector pump.
