Tracking the 914 - Need some street love too..., Turning this into a regular thing... Options

Paul Abbot pretty much retired. You may be able to find another resource on pelican parts or rebuild yourself, most of the parts were available. Paul may be selling some documentation.

Do you have webers or PMO's? Weber parts are below-

I have some documents too if you need something. I recently converted to EFI but I don't know if I'd recommend if for more of a track car, its alot of work and the main advantage is more streetability and direct easy tuning.

Thanks all for the info, I've got a bit of an update, top end is getting torn down as we speak, will be checking and cleaning up heads and identifying cam, then putting her back together, inclusive of a new set of PMOs...

It's giving me the opportunity to see what's inside so that it can be put back hopefully finding my missing hp. I like her raw character now, maybe look at FI in the future as she becomes more street than track.

Trying to say away from the slippery slope while she's apart...

Ya it becomes a slippery slope, last year I had an oil change turn into a complete motor topside refresh with EFI.

If you are considering EFI, one thing to think about is ideally they use a different cam than carbs with more idle vacuum, I am running EFI with a carb cam. It works fine but I run it a little more on the rich side to make sure it doesn't get lean. It is still massively leaner/more efficient than carbs. I have found though there are a lot of smells that come from fuel vapors all over the car and also the engine breather.

Also if you need any carb info there is a ton on the Performance Oriented site- https://www.performanceoriented.com/history...uretors-on-911s

Ha, speaking of smells...

I want to replace the main fuel supply line (it has no return) with SS lines. The PO installed all oil and fuel braided lines with -AN fittings (approx 15+ years ago). I'm starting to get some weeping in the oil lines and fuel smells are getting stronger so time to replace those ASAP. I'm keeping with the AN fittings, I want to stay away from hose barbs/rubber hoses and clamps.

I have SS fuel lines, I bought the correct size compression fittings with the correct -AN ends. While reading the install data for the fittings (they are black anodized Al) I saw a specific warning not to use with SS tubing, as they will eventually leak. I forgot, different metals = corrosion.

I started looking for new compression to an fittings, which i found a few, but that also means the -AN hose end that connected to the SS fitting also needs to be stainless. I'm having trouble finding stainless hose end fittings (for nylon braided fuel hose)...

Am I overthinking this? Thoughts?

[Justinp71]

Hmm... that's a decent point. You need an electrolyte to make the galvanic corrosion and the fittings are coated all though the coating can flake off some (gas is not an electrolyte). I would be more concerned about the threaded fittings (al to ss). You can get electrolytes from external water if its in the rain. The corrosion is from electrical current flow moving from the anode to cathode thru the water, so if it stays dry its not really a problem.

I think I have SS lines (or steel?) and al AN fittings...lol.

Can you braze on aluminum AN ends with a material/metal that's an isolator? BTW hose barbed ends with EFI clamps can take a fair amount of pressure but I agree I don't like to use them around the engine, but will use them around the gas tank.
