Almost certainly coincidental. The initiating factor there was an incorrectly fitted spacer bracket by Air Transat's maintenance - the replacement engine did not seem to have the bracket as part of the kit and, likely under some pressure to get the aircraft out and earning again, they assumed they could use the old one without checking the part number.
As it turned out the design had been revised and the brackets were not interchangeable. This meant that there was insufficient clearance between the hydraulic lines and the fuel lines and the former abraded the latter until it gave way.
