                Yes, there is an adaptor for the oil pressure line

9151205                adaptor - pipe to block                   oil gauge

 

Sorry for any confusion – there were several parts to Terry’s question – oil filter, oil filter adaptor to block and oil pressure gauge block adaptor.

Okay, now someone explain. Is there an adapter that screws into the engine for the oil pressure line? Mark L

I broke a line from the sending unit one time and to "get by" for a few weeks used a 1/4 NPT  plug from Home Depot.  Screwed in perfectly with no leaks.  When I put in a replacement sending unit it threaded in easily with no leaks.  So, I assume the threads were not damaged in any way by the NPT 1/4" plug.  Thus, I never saw any evidence that it wasn't 1/4". Mark L

I agree with you, but this is an original 260 and all of the tools to remove the fittings were matched whitworth sizes and the replacement part is a BSP 1/4 thread.

The block was threaded 1/4 NPT on the three or four engines I’ve dealt with. None of them were the original 260 but I don’t know why Ford would have threaded that engine differently.

Actually, I think it is a BSP 1/4 which is quite different from a 1/4 npt. That is what I am trying to clarify.

Terry, pretty sure that oil fitting that goes into the block is 1/4"  good old American standard pipe thread.  Hope you don't have a problem because I think the fitting should have come out fairly easily.  Mark L

Hi Ron,

  It turns out Summit had the right adapter for the kit, the sales 
person just didn't know it. They have sent the adapter to me and it fits 
correctly in the block as well as in the kit. The only problem was the 
oil filter they sent me was incorrect - it hits up against the oil pan. 
Is it the ph3600 that is slimmer and fits that kit?
  I also found another problem - the oil line from the oil pressure 
gauge was cracked and leaking. when I disconnected the oil line fitting, 
I also took off the fitting that goes into the block. It was very 
difficult to get off and I am concerned that someone either put a 
fitting in there with the wrong threads or stripped the threads when 
they installed it. Do you know what size those threads are? It appears 
to be a british standard pipe thread. I had to use whitworth wrenches to 
get both the pressure fitting nut and the fitting to the block off. Any 
info on these fittings would be much appreciated.

Cheers, Terry
