(IMG:style_emoticons/default/smash.gif) '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! |

that's what I do! Group: Members Posts: 20,065 Joined: 27-December 02 From: Port Hope, Ontario Member No.: 26 Region Association: Canada |
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. |

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! |
