Banjo Bolt - o-ring? crush washer?
I am beginning to gather parts for my e-fuel setup and think i'll go with the banjo bolt adapter from this thread: https://www.ford-trucks.com/forums/1...l#post13871919
the part itself is not cheap ($20 from McMaster or Parker, reportedly $12-15 elsewhere), but I figure it should save me at least that much in new fittings and stainless tube and probably much more than that in time.
my question is - does the stock banjo bolt have O-rings to seal it to the fuel pump and metal ring of the fuel lines? I'd like to replace all these sealing elements while I've got it apart and thought someone may know the size and type of such parts off-hand.
thanks!

Aren't the fitting that go into the rear of the heads AN fittings on 1/8" npt adapters? If so,I figured there are no o-rings there to wear out so I'd leave well enough alone and save a few bucks.
I plan to do this setup on the cheap, but def pressure test the system on the stand before installing the engine.

Well that changes things. I thought it would just be a flared end on the tube end connecting to the npt adapter.
It really would be a pain to have a leak back there after putting the engine back in. I will pressure test on the stand, but maybe new lines back there are in order after all.
Those threads in the heads (front and back) are 1/8 NPT, though, right?

the rear stock line seals can be replaced without tearing much out. I just dont like them IF I am redesigning I am eliminating such things.
the factory fittings Bill uses 5/16 line ,compression ferruls and nuts then builds hard lines forward. I did not do mine like that but after doing it my way,I like his much better.
Yes the head is 1/8" npt

Yeah, knowing there're rubber seals in there, I think I'll nix them as well. Those seals are probably only rated for 10 yrs or something anyway. I tend to hate compression fittings, but that may be an irrational hatred based on the ineptitude of whoever connected up my heating oil tanks :-)
Maybe I'll think about flare fittings. Bill - did you use stainless or copper? It looks like the stock fittings are brass back there. Hard to tell on the lines - I haven't degreased yet :-)
