Wet fuel pump. (?)

Here's the setup:
Garage has been smelly for a couple of weeks. Havent driven the 911 much (work, busy kids, etc...)

So I take it out yesterday, and I notice a trail on the ground from the front end.
OK, so that's where the smell was from.

I found a couple of posts detailing the process of changing out the hose from tank to pump. Went & picked up some fuel line and clamps, thinking this will be a relatively simple deal.

Got time to pull the pan under that area, and found that the line between tank and pump is bone dry, but the pump itself is dripping.

Banjo bolt area is crusty rusty looking, and difficult to tell where the leak is coming from.

Do these pumps develop leaks from the casing / body of the pump, or should I just try to source some new crush washers and take the whole works apart & try to re-seal the thing.

Of course, there's a full tank o' gas in the car. Figure I'll just drive it til nearly empty and then deal with it.

This is an '85 911 by the way.

Any hints, tips, tricks?

Also - have seen "reasonable" priced new pumps on fleebay. Are these worth considering? What's best bang for the buck? Assuming that I'm budget conscious.

Thanks in advance for any help.

Most likely weeping at the connections, if you are going to replace the hoses, I would consider swapping the check valve while you are there.

Drive her close empty and raise the passenger side, this will help keep the gas to one side as you work on her, Jack stands for safety sake.

Make sure your work space is free of any ignition sources and disconnect the battery.

My pump leaked after I discovered a chafe line in the housing - caused by deteriorated rubber mounts installed rather roughly by a PO.
The pump rubbed against the metal guard plate; a tiny weep ensued.

No way was I going to drive the car after I saw fuel dripping out. If you stop at the lights where someone has tossed a cigarette end...your gonads might not thank you.

I replaced my pump last week. It was leaking not from the lines or connections, but from the edge/seam. So to answer your question they can leak ufrom there. I don't know how common it is though. If yours is crusty around the banjo it could be the source. When I had the car at my friends shop I turned it on while he was in the pit below it and he could actually see the fuel seeping out.

I bought a new OEM pump since I figured the original lasted 26 years it wasn't worth buying an ebay version to save $100.

Good luck. When I changed it the hose came off of the tank when I was trying to get it off the pump. Spilled a bunch of fuel. I suggest you keep a bucket around to catch fuel and keep your work area clear of any hot lights and extentions cords. Other than that it was an easy enough job.

Thanks for your experiences, guys.
I also see that the check valve is a separate unit. Seems like this may be the problem, as that end of the pump is where it seems "wettest".
All new valve, cap nut and washers will be a good place to start. (With a low tank, of course).

Thanks.
