hi guys,
i have 2 bosch 044 fuel pumps external mounted to my surge tank, initially when i fitted the bosch 'banjo fittings' with copper washers they were leaking quite a bit - i then tightened them up a lot more & they are still dripping but only slightly. the leak is between the actual banjo fitting & 2 washers i.e. it is not leak leaking from the thread side.
i am concerned that if i go any tighter that i might strip the thread, is there a trick here? maybe softer copper washers or some type of glue/sealant?
