MASHWell-Known Member I have a '75 350 motor fitted in a Toyota truck and I'm about to fit a 90 degree filter adapter plate designed for a Ford engine. This should make filter changes easier and also sit the filter vertically and eliminate the drain back problems I am seeing when not started for a few days. The adapter plate has a 22mm x 1.5mm nipple and usually holds a motorcraft fl 500 filter. The 350 uses a 13/16 nipple. The standard wix 51258 filter has no bypass and can flow 9-11 GPM. Has anyone got a recommendation for a filter with similar spec but with the 22mm fitment?
Your correct Jim . But thats the bolt in the kit and I will be making a 13/16" type to fit the Buick. The nipple on the adapter that the filter will screw to is 22x1.5mm
