Found this little hose had come off. Fixed the high idle problem ive been having See attached pic
But today it came off again. Its obviously a vacuum hose going to the fuel pressure reg but i didnt realise just how important it is until i did some reading on here.
This from sydneykid was most enlightening.. and scary
Sydneykid on FPR hose/boost guage install
There is no clamps on this little hose and no evidence there ever were so it makes me think nissan never expected it to come off. Its coming off when the car is on boost.
Anyone know why? i dont want to just clamp the thing on id rather understand whats happening because it could be pointing to something more serious?
Car is R32 gtr, 1989, 1.0 bar boost, stock computer, aftermarket turbos recently installed which were rebuilt and highflowed r33's.
