'73 1.7, D-Injection, fuel pump moved to front.

Working with the two fuel lines that come from the tank thru the tunnel. One is large, one small. Since most of the lines in the front were corroded and full of tar, (all replaced), I must continue to clean/replace them at the engine site. Car sat for over 30 yrs.

Correct me please, brother Haynes is not very clear. Large fuel line connects to (1) Pressure Regulator, Cold start Valve and Injectors. Not sure of location of Pressure regulator. All the regulators/pumps mixers look alike. I think it is near the injector, passenger side, mixing tube.
Small line connects to Pressure Regulator.
Thanks for your help!

this is for ljet 1.8 but you get the idea

Tank with screen, to filter, to pump, to big line, to 3/4 injectors, to cold start valve, to 1/2 injectors and finally to the regulator and return line.
All hose in the high pressure loop (pump to regulator) must be FI hose, I just use FI hose for the whole system.
Always use FI hose clamps, NEVER the standard worm gear style hose clamps.

Beautiful! Much appreciated!

Good! Some hose clamps were slotted, worm gear. I replaced those with solid, FI clamps. Used many of the original clamps. They have a tiny VW stamp on the band.
Thanks for this helpful reply!

large tank to pump= supply
large in tunnel to injectors = delivery
small from regulator drivers side to in tunnel = return
up front under tank return and bypass- T = return to tank

Great help! Getting near to turning the key after 30+ years. Now.
need to put some Magic Oil in the cylinders. How do I get to them?

And how can I hand-crank the engine/

Like looking at a Rembrandt.
