What alternator belt have people with the following combination got fitted: K series Apollo tank Brise alternatorThe 5PK738 is way too small, can't get enough rotation on the alternator as it fouls the pipes coming off of the sandwich plate so has limited movement. Not sure the 5PK778 which was previously fitted is small enough, it's tight but I'm sure it could be tighter! If anyone has an apollo and brise, let me know what belt you've got and if it's the 5PK738 what magic you worked to get it on
