I ordered an 04 aviator fuel pump today to replace the 255 walbro in my car , the walbro has been hanging in there but I just dont trust it , holds 42 psi full throttle when half warmed up now (28psi at idle )and about 45-50 after its good and hot at WOT , but the aviator is supposed to be better and designed for the returnless fuel system so I ordered it from a local dealer for $180 bucks , cheap insurance if you ask me , this is just to hold me over until I get the paxton intercooler and a few other goodies from T&Js in a few months , just wanted to let you guys know ahead of time that I will post my results of this pump and my opinions after the fact , wish me luck guys ....
