22r (not RE)-3.4 fuel delivery questions
I've got an 1985 22R (not EFI) truck that I am almost done swapping in my 3.4 into. Luckily, I purchased much of my supplies from ORS before the shut their doors. My question is what are you guys doing for fuel delivery.. lines, pumps, tanks (fuel cells) etc??
Its my understanding that I could use the lines off a RE equipped truck, but I feel that custom made lines from the tank to engine would be easier to be made (more $$). What size/diameter lines would be needed for the main line and return line?? What fitting is the main line to the engine? Lastly, how much pressure/volume does the pump I purchase need to be putting out?
Thanks, and if any one wants me to post my build up I will gladly do so when it is all said and done.

I used the stock system from my 3.0, the only thing I had to do was use ORS's little blue hose with the adapters to make the 3.4 fuel line reach the 3.0's frame mounted line. As far as the specs on the stock pump, I don't really know, but I've heard of people using the stock RE pump, unless they supercharge. Maybe the FSM has the specs?
Edit: Found the specs in the FSM
Fuel pressure:
265 – 304 kPa (2.7 – 3.1 kgf/cm2, 38 – 44 psi)
