This line has the two fittings located right next to each other on the check valve as shown. Compare your line to this one to be sure. If you've tried replacing one or both of your broken fittings with straight vac lines there's a reason it didn't fix the problem. These aren't just plain fittings coming off of the check valve. Each one has it's own very specific internal diameter restriction as part of the vacuum system design. Any sort of repair is either too large or too small in diameter. Even more frustrating is both conditions often give the same symptoms so you will be always be chasing the issue. Aside from the erratic symptoms of an open check valve you are also compromising the function of your brake booster.
