a quick dumb question..... should my fuel accumulator be hissing like a snake when i turn off my ignition ? its brand new just finished rebuildin the entire car,,,it a bit lazy to start up have to turn the ignition on and off a few times to build up fuel pressure..... no sign of any leaks anywhere//////all i can think of is me tank cap is a bit loose.....would this cause me a problem/? anyone any ideas???
