The lift pump is the mechanical fuel pump on the side on the injection pump.
Possible but unlikely that the crush washers on the lift pump are leaking.
The pre-filter can be clogged or its o-ring way have deteriorated.
The o-rings on the fuel lines can fail to seal as they deteriorate over time.
Fuel may not leak out , but air can leak in if they are dried out from age and engine temperature.
Perhaps just replacing the o-rings and/or the pre-filter with its o-ring is what is needed?
The car is 21 years old, when were they last replaced?
