Bought a 1988 Supra Mariah with the 454 and only 310 hours from an estate. Unfortunately all of the service information was lost with the former owner's passing. I would like to perform a complete service on the motor - oil and filter change, fuel filter change, new impeller, etc. I have had almost zero luck finding the correct information to order the new impeller and filters. Can anyone point me in the right direction? Any help would be much appreciated.
