Fuel System Pressure Release

  1. Loosen fuel tank filler cap to relieve tank pressure. Remove fuel pump relay from underhood fuse/relay box (Amigo, Rodeo, Passport, Trooper and SLX), or from behind glove box (Hombre). Start and operate engine until it stalls. Crank engine an additional 30 seconds.
  2. Loosen hose clamp of fuel line on side of pressure regulator, coming from fuel line inlet distributor pipe. Cover fuel hose with a shop towel, and slowly pull hose from pressure regulator to relieve fuel pressure. When fuel stops leaking, reinstall hose and clamp.
