is there any way to fix 1974
 

leaky fuel accumulator leaks on bottom right by the little screw
thx in advance

Some images will help.

Best,
Grady

or get a new one prior to the fire.

why then i could sell it for parts here and probably make more than the car is worth

if you need an image then you probably cant help me because it never happened to you then its a stock accumulator that has a little screw on bottom and its leaking drops thru there
thx

The right way - replace the fuel accumulator...

The cheap way - take out the fuel accumulator and a seal up around where its leaking with a gasoline safe sealant. Gas is a great solvent... so I have not idea what you should use.

Personally I'd go with option 1. In either case, be ready for a fair amount of fuel to come out of the lines. I just did my fuel pump, accumulator, and filter, and there's an decent amount of fuel that stays in the system. Having a disposable container (water or soda bottle) to collect the fuel from the lines will help keep the mess down.

Also, while you are in there, change out the fuel filter.

If it is a stock accumulator (Bosch 0438170015) then there is no "little screw" - at least not on my 30K 2/74 car. Of course it may be different on the "930 slant nose" variant.....:rolleyes: Give us some details and we'll be glad to help you. -John

Mine also recently developed a leak in the same location. I removed the small screw, cleaned up the threads and replaced the screw with a little 3M liquid pipe thread sealant. I made sure the screw was well tightened. The leak has been fixed.

I also have a pressure accumulator from an 81SC which has a hose connection at the bottom (in place of the small screw) which connects th the fuel return line to the fuel tank. I understand that this is to drain any fuel that escapes past the diaphram/spring? in the base of the accumulator.

I guess there is a possibility that the diaphram in your (and my) '74 accumulator may have developed a leak past the diaphram into the base area.

I am going to remove mine, remove the small screw, seal the normal outlet and pressurize the inlet and see if pressure is escaping past the diaphram. If so it will be time to replace.

Good Luck - Steve

steve you seem to know what im talking about when you took out the screw was there any rust or just gas.and when you put back did you put back the same screw
thx mike

this is in a 1974 911 just like the ad reads and the part number is 0438170015 and yes it does have a little screw look up on google and you will see it
thx i think ill just clean it with a little air and carb cleaner and take steves advice
thxfor all your help

long horn why would you change all those things was your car having trouble starting or something

Fuel pump was definitely bad... bypassing the relay would only cause it to intermittently work, so that had to go.

Fuel accumulator was old, and easy to deal with at the same time.

Fuel filter because its supposed to be done every 6k miles, its cheap, and I was in there.

heres the image 1973 1974 1975 1976<a href="http://tinypic.com?ref=28rgu3r" target="_blank"><img src="http://i51.tinypic.com/28rgu3r.jpg" border="0" alt="Image and video hosting by TinyPic"></a>

oh ok was it hard starting

Actually part number is 477-209-083-M14

usually if it leaks you are also having a problem with warm/hot start.

it's a $117 part - you can probably thank ethanol for the break down in the diaphram.

Carry a fire extinguisher, I would not transport anybody you really care about. Where the accumulator is - makes it easy for gas to pool - then drip on the heat exchangers - then the excitement can start.

Um, do you have any idea who Grady Clay is and what he knows about our cars? As the old cliche goes, he has no doubt forgotten more about these cars than many of us will ever know.

You might consider apologizing for dissing him in a very public forum, to which he contributes regularly and with great skill.

Hi Mike. Yes I put the same screw back again. The screw was rusty but cleaned up OK. I screwed it up as tight as I could with the sealant and it has been leak free for a few months. As indicated before this may be indicating a further problem and as others have recommended, replacement might be cheap insurance. - Steve
