Dropping 83 911sc motor, stuck on a fuel line...
 

Hello, I'm dropping the motor out of my 83 sc which was going pretty smoothly but I can't seem to figure out this fuel line connector.

On one side is a 17mm nut that appears to be fused to the aluminum fuel line. On the other is what looks like a screwed in termination with two flat sides. The sides don't really match well with any metric or standard combination wrench I have. I can used a thin crescent wrench on it but it is not a good fit, almost as if the flats are not quite flat. I have applied force to it this way but was not able to get it to break free. I didn't push it too hard since the wrench does not feel like it is seated too well.

Besides a couple of minor electrical connections I believe this and the transmission is all that's left to drop the motor. (I've been using the 101 projects book as a guide).

I have attached a picture of the fuel line with a circle around the odd connection. Any clues are greatly appreciated.

Break the line closest to the engine.

Is there a special sized wrench that fits better on the weird hose side of the fitting or should I just make due with an crescent wrench?

Thanks,
scott.

One side is a 17mm and the small flat is 12mm, but that small side is loose so it could be an 11 before there was 30 years of installings.

+1 I just did this a few weeks ago and I thought to myself "this can't be oem..." but yours is just as twisted as mine was! :P

I don't think that hose is available new from Porsche any longer, but you can replace it with one that I make from standard Metric fittings. No problem getting a flare nut wrench on these.

Heres a similar one that I make...........

to replace the hose at the fuel accumulator on 911SC's that I know is NLA. Of course your hose would have a straight instead of the 90 fitting shown. These are made to order, so any configuration is possible.

Scott, that fitting is the worst of the bunch. Here's my adventure with it. Good luck!

You can always cut the hose and deal with the fittings once the engine is out. All the rubber fuel line bits ought to be replaced anyway. On my 1988, I was really shocked at all the cracks in the fuel lines ...

You can just get FI hose from FLAPS (you need 2 sizes - the SAE stuff in 5/16 & 3/8 (I think) will work, metric is a better fit but harder to find), along with FI hose clamps (or oetiker clamps) and replace the rubber bits yourself - I assume the SC is similar to the motronic in that regard. Or get your lines "remanufactured" with crimps - just make sure they're factory style crimps, not straight hydraulic hose crimps.

If you just want fittings or hose, I have the right stuff.

Everything is sent US Postal Priority Mail w delivery confirmation. 2-3 days coast to coast.

The factory design had the twist. It is the return line on the system and if the 78/79 twisted it could cause the pressure to go out of control.

I could not break either end loose when dropping engine and ended up cutting it.
