74 1.8 - I previously replaced the 3-port fuel pump with a 2-port pump, mounted to the engine firewall. I have since sent the 3-port pump in for rebuild and have it back.
I have been fighting fueling issues for a long time - fuel pressure drops to 0, engine bogs down/dies. Wait a couple minutes and starts again. I'm down to assuming that there must be a fuel line kink, or a fuel line collapsing somewhere. SO - winter project - All New Fuel Lines. I need some help from the collective brain trust please. Do I: 1: Move fuel pump to frunk by spare tire, stainless lines thru tunnel, new rubber lines everywhere else 2: Leave fuel pump on engine firewall, stainless lines thru tunnel, new rubber lines everywhere else 3: Revert back to stock setup with 3-port pump, stainless lines thru tunnel, new rubber lines everywhere else To complete the above - what do I need to order for the stainless line update, and who is the best to order from? Are they all made by the same person, or are there differences? (and do I need the reducing stainless line from CFR?) Thank you in advance for all the help - Steve |

2 port pump over 3 port pump.
Move it up front. Get and use the stainless hardlines for the tunnel. Get some nickel copper tubing and make some hardlines for under the tank. This will permanently resolve kinking issues. Use properly sized fuel injection clamps. Not the cheap worm drive clamps. Use proper fuel hose. DO NOT use the German cloth braid hose. Even if it says its ethanol tolerable. Get hose that is printed with the correct SAE cert for your application (at least 30r9 hose if you are fuel injected or 30r7 hose if you are carbed - though some makers warrant their 30r7 hose to over 100psi).
