Okay heres the deal . I just got a TRD supercharger and I am wanting to plumb up a new fuel delivery system. I've been reading other threads to get ideas but my situation is a little different.
The 03' TRD (M90) 2uz-fe 4.7L specific supercharger runs fuel to the 9th and 10th injectors. The stock fuel pipe I am provided with is rusted/corroded out and is bent. Plus I think I maybe missing one more for the rear and maybe the front fuel pipe that goes under the supercharger nose delivering fuel to the passenger side fuel rail - stock fuel regulator-return line that routes through the back on the supercharger (the other line I may be missing in the installation of the supercharger).
So The TRD supercharger usually makes 360 HP running 4 psi of boost. I'm gonna be running the Uni-Chip to get rid of the problems associated with the TRD piggyback also. But I am having problems figuring out how to plumb this system up properly using the stock fuel rail.
Overall what -AN size I should use so I don't end up changing/lowering the fuel pressure running a line that is too large Attatchment/picture provided of the stock setup connecting the fuel lines using a dual hole/dual feed banjo bolt
The fuel pipe looks like its just over 3/16" I.D (??mm?? equivalent inside diameter) . So this would techically be AN-3 sizing for the stock setup? As I was told by a previous Navy Engineer , Every AN- (Army Navy) # more is done in 1/16" increments. The Toyota Tundra's fuel pressure is listed in the Toyota Repair manual as 38-44 p.s.i. @ idle.... with the stock size, whatever ist really is. So if I do end up going to AN-4
sizes in the hoses/adapters, clamps, etc. Would this change the fuel pressures going through the entire fuel system/fuel rails using a larger AN hose setup running the stock Fuel Pressure Regulator?
So I'm figuring using a T connector or Y-connector ( don't know where to get these ) to feed the 9th and 10th injectors plus feeding fuel to the passenger side rail off the drivers side fuel rail. Is this do-able or is there a better way. I need some help to get this running right.
