I have a 1991 Subaru Liberty which was owned by my Great Aunt from new. Its first fuel pump lasted about 19 years. We have had the car since 2009 and it has had 4 fuel pumps in that time, now requiring its 5th. I've used original and non-original parts and nothing seems to make any difference. Between 12 and 16 months the fuel pump stops working.
The car does approximately 4000kms a year and has done 137,000 in total.
Does anyone have any idea what could be the problem?
One faulty fuel pump I could understand. But I cannot understand 5.
This is my first ever post on any type of forum so I apologise if I've posted in the wrong area or done something else that's incorrect.
