Jet fuel played a negligible role in the Lockerbie attacks, other than elevating the target to where pressure and airstream would rip the hull to shreds.

The initial bomb damage was a 50cm (20in) hole. Disruption of control systems (steering and stabilizer cables) lead to a pitch of the aircraft, aerodynamic forces of a 500kph (313 kn) airstream tore off the nose of the aircraft, parts of which impacted with and initiated further disintegration of trailing portions.

Again: fuel did not contribute to the damage inflicted on the aircraft.
