I purchased new fuel accumulator supply and return lines as well as a new accumulator. I removed the two connections on the top and when I remove the bottom flexible line fuel keeps coming out of the line. I let it go for a while and it keeps leaking fuel so I cannot replace the flex to hard line nor the accumulator. Am I missing something or doing something wrong? I believe this line is the return hose correct? Also being that the connections are fuel oriented I assume that here is no need to put thread sealant on the connections correct. Just tighten as tight as possible. Any tips or advice would be greatly appreciated.
