i believe as mentioned your car is a return style so the FSVT pump may not werk ! talk to Bill Jenkins @ teamfordparts.com !
if the disc-screen is there , GET RID OF IT !
i would think the fuel filter would affect the drivability despite what level of fuel your tank contained , but it's cheap , so maybe give it a shot !
good luck , let us know if you switch it out via the back seat & how that goes !
to disconnect the centre-lap belt there is a small hole in the clip that you need to insert a small allen-key & press on the mechanism to release !
the 0-ring is part # : XS2Z9276AA ( cheap @ teamford..... )
