The fuel pump in my 74 1.8 L-Jet seems to be dead. I plan to pick up the Bosh single inlet/single outlet pump at Napa (Part Number: BSH 69133). The dual relay at the battery checks out good, and when I turn on the ignition, I get a single click from the fuel pump, but no priming/whirring sound - and no fuel delivery. Engine will fire if I squirt a bit of starter fluid in the intake snorkel, then quickly dies.
What exactly do you need to do with the 3rd fuel line on the current pump? I've found a few posts that simple say "convert it to 2-line pump", but I'm out of my depth with knowing what to do that won't compromise the car's, or my, safety. I searched but couldn't find any drawings or pictures of how to route the lines, or what to do with the 3rd line. Any detailed advice would be welcomed! Thank you, Chris |

No need to move your pump to the front, just relocate to the firewall. I moved mine 15 years ago and never had a problem. The original location is just too damn hot for a fuel pump.
Chris at Tangerine Racing is great. Got my steel tunnel lines from him. Get new rubber grommets too for firewall. Here is link to video to install lines: https://www.youtube.com/watch?v=hxFRQTWLetw There are two plastic fuel lines that go from fuel pump to engine bay that probably needs to be replaced too. Chris has those too. Replace fuel sock in tank too. I had to get a fuel line adapter piece from Chris too. Good Luck! Attached image(s)

I am in this exact situation with a replacement bosch pump.Does that fuel filter in your picture solve the problem of the 1/2" inlet of the bosch pump. What is the dimensions of the in and out ports of the filter. Do you know the p/n by chance and where you purchase it. Thank you |
