I replaced my fuel accumulator years ago and it's been fine ever since. I put a flexible line between the high pressure outlet of the accumulator and filter as my hardline developed a pinhole leak. That's been good too. What I never got around to doing at the time, was replace the short, flexible rubber hoses at the accumulator. One of them is the high pressure hose that connects the hardline coming from the discharge of the pump to the inlet of the accumulator. The other is the lower pressure hose that connects the "relief" or discharge end of the accumulator to the return line tee fitting.
It's this return line hose that connects to the accumulator and tee that I would most like to do as it looks to me like it is weeping or split in some way. I can see on the accumulator end that it is just a simple metal clasp holding it on. On the other end of the hose, at the tee, it's harder to see (and reach!) but according to the parts diagram, the hose pushes onto a barbed fitting and may or may not have a clasp on it.
To try and make life easier, I was thinking this hose could be pulled off, or cut off, of those barbed fittings (once the clasp(s) are removed). Is there going to be any need to mess with that nut and barbed fitting itself on the tee? I'd just as soon not have to loosen it and then try and get it back together and sealed up.
Another thing I wanted to ask was what kind of precautions do people take so that you don't get an entire tank of fuel dumping out all over the place once you get that hose out? Is there a real possibility of the fuel syphoning out of the tank and coming down that return line, either from the tank or via the engine? I can deal with a little bit of fuel that is in the hose or return line, but would rather not see anymore fuel spilled on the garage floor than I have to.
In the back of my mind, I'm not entirely sure how this little rubber hose could be leaking or split and not be seeing it drip fuel constantly. That tee and barbed fitting has no check valve in it to my knowledge. It sure looks like it's leaking a little, but if it was leaking a little, I would have thought it should be leaking a lot. Yet it doesn't seem to be as there is never a big fuel puddle under the car when parked.
