Ok so i found it on line part number 275500455 and Everywhere I found it at is $41.99 so thinking to myself that it is at the bottom of the The deepest parts of hell ... One would might go ahead and pay that although I am needing several other parts I’m sure for this RXDI, A light bulb came on this morning in my head . I took a two dollar piece of steel and just made one see pictures below .... so if anyone is in need of the same part is having trouble getting it out and can gladly sell you one for $31.00 and EVEN include free shipping Lol.... now i can get back to being completely lost on what to do next......now i’m getting 90 psi’s ( I believe the manual says it’s supposed to be 107)... from my fuel pump and off the air compressor,i didnt use a T ,but just attach the gauge at the end of the hose going from the air compressor line going to the fuel rail and I’m getting on the 60 PSI’s ,I believe the manual says it supposed to be 90+ or -2there and not sure what to do next..do i need to rebuild the air pump?... I believe the owners manual says you have to literally get into the bottom of the motor to get to it is that true ???
