The PO had a single carb on when I bought my 74’ 1.8 914 and said he had uneven idle problems with the L-jet injection so he preceded to remove all components and box everything up. So now I’m feeling I want to reinstall the injection and put it back to stock. I have some mechanical ability and patience, though I was never able to get that gas smelling carb to run right. Was looking for someone I could pay for a few hours to kinda orientate me on the location of the box of injection parts I have and give me thoughts on what parts I might be missing and how difficult and expensive it will be to put everything back. I’m in Puyallup WA south hill area, Thanks In advance

Not a bad thing to do. Sometimes these cold start valves leak and will cause a rich running condition. Your box of Ljet parts looks beautiful, but it is concerning that is was removed for some reason. So it would be wise to be proactive with checking most everything before bolting these unknown parts back on.
I haven't followed your previous posts, are you building a concours mint 914? Have you already replaced the plastic fuel lines in the tunnel? This may be argumentative to many, but I would ditch the 3 port fuel pump, and relocate the new fuel pump up front. |

Definitely not concours but keeping everything as stock as I can. Was thinking about getting the 2 port but not sure about relocating it to the front yet. A quick test on the FI harness showed a bad wire and more then a few brittle and cracked. I’m betting the PO was fighting that maybe. The hoses on the injectors are new but did notice not much of a bend on them. Was mainly looking for info on what is directly beneath the plenum so I can buy those parts and get started with the installation soon. Thanks |
