Folks,

Went out to a recently restarted 914 this am to grab some tools and noticed a wet spot under the car -- passenger side. Big wet spot. I'm thinking hmm I don't recall any rain--hmm--what's that smell??? It's gas of course.

So I'm about to go look closer -- is there an easy way to pinch off or plug the incoming gas line while I sort out the real leak?

What year car? If it is an earlier (i.e. the fuel pump is back by the engine) THen you might have noithing more than a loose hose clamp on your pump. Best thing to do is don't start the car. If you have someone there to help you, put on some glasses and have your helper turn the key to on (this will run the fuel pump for a second). While they do that you look to see if there is gas coming from the fuel pump. If so try tightening up the lines/clamps. If not you will have to do more digging.
Side note: to see the fuel pump clearly it is recommended that you rtemove the flexible heater hose connecting your heat exchangers to the body on the passanger side.

Good Luck

While your digging in there it aint a bad idea to just replace all of the lines with new ones from your local FLAPS, the only one that is special is the one to the fuel filter (which might also be the one leaking) it starts I think at 9mm and tapers to 7mm, so that one you gotta buy from the good folks here at Pelican. Also get a fuel filter if you haven't in a while and just give the whole area a once over.

Are you really Karnak? That is exactly what I've done.

(i.e. filled up on Sat, and parked on the incline driveway to wash it)

It happened to me recently. Topped it up to the very top, wiggled it, and squirted in a few more drops of gas to really fill up. Drove it the 3 blocks home, parked on an incline... and in the morning I thought I was driving a molotov cocktail on wheels.

I dont top it off anymore. (IMG:style_emoticons/default/mueba.gif)

Hm. I don't top off. But each gas station has different pump handles and who really knows where the quit filling? This time, I filled up at a station I don't normally use, so it could have been a higher top off. (making this up of course)

So what is actually happening tho? The tank is way up at the front. The leak is way at the back. If the tank is overfull, wouldn't it drain off somewhere up front?

I've been assuming that, since mr yellow hasn't been out recently, that the wake up knocked some old crappy line or something and it decided now was the time to smell up my neighborhood. (I'm loved, of course :-)

Is the leak coming from one of the carbs? Can you tell?

Oooo, I love this. Popped the air cleaner off -- carbs are wet on the sides.

So.. that tells me:

Fuel tank up high; Carbs lower; Gravity pushing fuel from tank to carbs.

Are the float bowls overfilling and spilling fuel over somewhere?

What kind of fuel pump are you using? Stock or aftermarket?

Got it.

If I siphon out some fuel, it should stop then.

re: fuel pump -- dunno. Never looked at it yet.

Lawrence & Kim,
It seems to me that the float valves should have stopped the flow unless there's a leak in the line, a stuck float valve (BTDT) or a passage that allowed gas to escape from the carb.

Hm. If I actually look at it, there is definitely fuel from the float. But I"m not sure there is enough to be causing what I see on the bottom.

So I'll put it on stands and look at the bottom a bit more. If it's sneaking down from the carbs, I should be able to see that from underneath.

More as I dig.

Thx for the assist! (I love this bbs)

Well, it's of course possible that the gas on the carbs (a new thing, but with the stock air cleaner on, not visible instantly) could be a separate problem. That would mean that I have two problems. Hm. Better and better!

Thx Carl.

I assume you looked good and hard at the line between the banjo fittings?

Kim,

Have you had the carbs apart recently?
