Looking for opinions

74 dodge dart sport I plummed my braided fuel line to elec fuel pump then had my 3 inch exhaust put on yesterday and the passenger side muffler ended up about a 1/2 inch from the electric fuel pump and about a inch from the passenger side air shock bag I bought some 1800 degree header heat wrap if I wrap the muffler and exhaust pipe will this keep the fuel pump and air shock from getting to warm thank you
