Spin On Oil Filter Conversion Kit

Catalog list this part as "48-56 F1-F350, all engines with element and canister." This adapter will not work on 226 flathead engine with canister, seems that it only works on some V8s

Not good. First off there were no instructions. When I mentioned this, one guy told me I didn’t need them, then another guy piled on and said that I don’t need directions because they’ve been selling the part for years. It’s a large fitting that had to be removed. I had to figure out it was 1 1/4”. They sent me a link that was ‘supposed’ to help. The link brought me back to the part I had ordered. Not very helpful at all. I got everything together twice and it still leaks like a sieve. Now I have to get the car to a professional to get this together because I am fed up. I give customer support a ZERO. I give the parts themselves a ZERO. No, I don’t think I’ll be ordering from NPD anytime soon. You got one star because I couldn’t leave none.

This kit is comprised of 3 pieces, and they only go together one way to accommodate an FL-1A filter. The customer did not recognize that he needed to remove the original fitting from the block in order to install the new fitting provided in the kit. This was the original issue. I tried to explain, provided photographs on a display Y-block in our collection that has this kit installed on it (by Ford, it is an old Ford show/display engine), and apparently still to no avail. While we regret the struggles that were experienced in this particular instance, I can state with honest assurance that NPD has sold over 1,000 of these kits over the past 20 years, without issue or need for instructions, until now. In fact, this kit is a reproduction of an old Motorcraft conversion kit that Ford offered dating back to the 1960's (Motorcraft FL-766). Ford never provided instructions either. Just a bit of historical context.

Gasket is like a large rubber band. The gasket that came off was thicker and wider. Needless to say I’m still leaking oil.

Excellent conversion kit. Stamped steel is well made and thick. You must use a 1 1/4” THIN wall 1/2 “ drive socket. You must hold the plate to the block to keep it from turning while tightening the 1 1/4” nut. Make sure you have the top of the plate marked TOP facing out and up. I glued my gasket to the plate and then put a paper thin coating of black rtv on the gasket where it meets the block.

This part is junk and should not sold. The flat rubber gasket will extrude inward when tightened and cause big oil leak. This is inadequate for a face seal and should utilize an o-ring and o-ring groove. If you search the internet you will see many people complaining of the same issue.

Again, we will reiterate, this kit is an exact reproduction of Motorcraft FL-766, a conversion kit engineered by Ford that was introduced in the mid-1960's. So this kit, in its exact same design, has been successfully used for 6 decades now. Tens of thousands of them. And I've never seen a classic oil filter with a round seal, so why would you expect a round seal for this type of conversion? I would have to imagine that the engineers have good reason to use flat. There are numerous 5-star successful reviews above, some with great installation tips.

The gasket that comes with this is useless! I used Permatex gasket maker that sealed it .
