Fuel leak from the bottom of the car! Please help!

[spikeygg]

I got it out after finding this article and saw that the little nub stays on the hardline. I "popped" it with the 17mm wrench as the article says and it let loose from the fitting. Anyway, I pulled everything down and disconnected the hoses. Upon inspection I don't see anything in the rubber that would have caused the leak. I'm wondering if it could be the barbed fitting sticking down from the top. Any suggestions on if (or how) I should replace it?

First of all- Those are *excellent* pictures. They really help show the accumulator well for someone who has not worked on it yet.

Second- Start easier, then go harder. Replace the hoses before messing with the lines. That line is between the frame and body, but there is supposed to be a small access panel under the center console you can see it from. (I have never messed with it, but I've seen other posts about it) The metal line is just a barb, so there is no reason for it to "break".

Third, you have worm gear clamps on those lines. Not fuel line clamps. I'd get a box of the correct style of clamps from the auto parts store to go along with the new hose.

Thanks jackb, I appreciate the feedback on the photos -- when I make a post I try to get a good shot that explains what I'm talking about . I replaced all the lines with EFI hoses (5/16" for the high pressure one, and 1/4" for the low pressure one) as well as EFI hose clamps, as per your suggestion and ... VOILA, no leaks!

Thanks everyone for your help with this.

What pressure are the hoses rated at?

+1 I was wondering the same thing. I searched the SAE 30R14T2 code on the hose and it seems to be rated for 100 psi. If so, I believe these hoses should be rated higher. For example I chose Gates Barricade 4219BF,which are rated for a max working pressure of 225 psi.

Also, if not done already, I recommend that you research the torque spec for the clamps ( it will be in inch pounds) and ensure they are tightened properly.

If he used Gates Barricade greenshield hose SAE J13R14T2. It has a working pressure rating of 225 psi. About 4X more than the most it would ever see in the Delorean.

Sure, and I guess the SAE 30R14T2 part number visible in the picture is the low pressure return end of the accumulator. So the other hose is what's important. I bought 225 psi for both hoses and 4 fuel injection clamps. I figured this was another area on the car to get higher rated parts.
