1zzfe Fuel Pressure Regulator

[ae924afdx]

I am installing a 1zzfe in without using the stock Fuel pump assembly that comes with the FPR {fuel pressure regulator}. I have an msd in line fuel pump that is capable of suplying the 45psi needed for the 1zzfe .

I wanted to know since the 1zzfe doesnt have a return hole in the fuel rail if i can install an aftermarket FPR before the fuel pressure rail?

Have anyone seen a mod like this one done with a 1zzfe?

Any ideas or suggestions?

Thanks.

You cant, because theres no return line to the tank.

yes .. on my ae92.. that where the 1zzfe is going.

Why didnt you say that on your first post.

Then its just a matter of getting a fpr that connects between fuel hoses, however I dont remember if the 1ZZ-FE rail has two hoses, because you need to put it on the return side of the fuel system. if it doesnt, then just get a fuel rail made

i found the answer on this website... just like i tought put the fpr before the fuelrail hose. and give it 45psi stable at all times. Weird system but thats how the new toyotas work. from the fuel tank i am going to use first:

. in line fuelscreen {strainer} , external fuel pump, fuel filter, {all of this near the tank..}

Then by the engine bay: FPR .

That shoudl take care of it hopefully.

thanks for the help. And of course i am going to replace the fuel hose with fuelinjection high pressure grade hoses.
