Just follow my post from earlier today and you'll know 100% whether your accumulator is bad. All you have to do is loosen one screw on a clamp that is easily accessible, pull the rubber hose off, block the hole so that the fuel from the tank doesn't gravity force itself out, then start the car and see if fuel comes out of the drain line. If it does, then you are 100% sure the accumulator is bad. If you use a check-valve in its place, you'll negate the reason the accumulator is there, which is to prevent vapor lock and to enable hot-starting, by lowering the fuel pressure "gradually" when the engine is turned off.

$110.00 is a good price. The dealer sells the part for $394.00. You can find even better prices on the internet. Just google "fuel accumulator for whatever year and model yours is.

If you're having the hot-start problem, this is a very simple way to figure out if it's your accumulator, and there is no substitute for replacing it. The system was designed with the accumulator, not a check valve. A check valve likely won't solve the problem since it won't hold pressure on the system at all, and the vapor lock issue is caused by the fuel pressure decreasing rapidly when the engine is turned off.

Good luck. Don't make it hard.
