Ford Lehman sp135 secondary fuel filter

[paulga]

Is this oem filter compatible with the sp135? it's said to have a better design and easier to change filters.

if so do I need to purchase two of these filters to replace the existing Baldwin spin-on filters?

I plan to change both racor and secondary fuel filters for a FL sp135 engine. the previous owner has multiple spare filters shown as attached. For racor filters, I'm going to switch from 30 micron that has been used all along to 10 micron.

For the secondary filters, I have two Baldwin bf825 spare parts. I could just use them, but I saw many threads highly recommended to use R12s filter as the secondary filters. One example is here.

Before proceeding I would like to post my question here. Is this R12s also recommended for FL 135? If so what adapter is required for installation?

asked ADC. the answer is no (unless with some material modification) for sp135
