Its going to be straight into the AFPR. Which will be chassis mounted.

Looking at this doc: https://www.swagelok.com/downloads/W.../MS-01-140.pdf

The pressure fittings are rated to the working pressure of the tube (page 9)

I can get -500-6-5AN (page 19) which is a 5/16 tube to Male 5an. Then a simple 5an female to 6an male and were good to go. Need to call a distributor and get a price.

Then I dont have to **** around with flaring and stuff.

 

I very much hate those fittings. The necked diameter next to the large shoulder means they snap off in your block oil feed port.

 

Thats different than what he posted. You linked to a tube fitting, like the PDF I linked to

I need 1/8NPT. I might do that too though. Still shopping.

 

So it is.

I'd still use that one over the male/female adapter you linked. AN fittings probably don't need the thread relief the M10 does, but it's still a very shittty weak fitting IMO.

 

 

What male/female adapter? The one ian linked?

 

Yeah.

Seeing the picture of the swagelock, it probably doesn't matter. It has a weak center no matter if it's male or female.

With the need for the through hole, combined with the thread relief cut right into the shoulder (can't turn complete threads against such a tall shoulder) means you get a really weak shear point.

 

Then there is this if I can't find the swaglok fitting.

www.ka-t.org ? View topic - How to *properly* run AN fittings with stock fuel lines

 

Why would you screw an AN male thread into a block oil feed port?

I have a couple of these fittings, but I use them to put a pressure sender on the chassis and run an AN line to them. Like this:



There shouldn't be any significant load on the fitting in this application.

Does that fitting have a flat spot for an o-ring? It needs to seal against the block.

 

Are you asking me? Which block? Neither end is the right threads for the engine block -- do you mean the FPR housing?

I dunno if it's got an O-ring spot or not. Here's a slightly different angle shot:



--Ian

 

Sorry, I meant seal against the afpr. See my picture a page back.

Before I dig into all this. How much fuel/hp can the stock 5/16 line support.

[Utag]patsmx5[/utag] are you running stock headlines?

 

I run 6AN feed and return. No stock lines.

 

Damn, you too?

 

I know we discussed it in Gs thread at some point.

 

IIRC, stock 5/16 lines are good for 300-400 on gasoline. You really only *need* -6 on a Miata if you're running E85.

(edit: with a turbo. supercharger may well be different due to parasitic losses)

--Ian

 

Yank is running 350 on e85 an stock lines I believe. Isn't the tank outlet 5/16 anyways?

 

I did it because I wanted to overdo it so I wouldn't have to worry about a weak link in my fuel system. I have a fairly ridiculous fuel system in this car, although I am running E85. Twin 255's, 2 relays w/10 gauge wires, 6AN, regulator in the engine bay, ID1000's at 60 PSI and 1:1 referenced. Basically a few months ago I got tired of upgrading things and not doing it "enough", so now whenever I upgrade something, I go ahead and do it all-out with the idea being it's the last time I have to mess with it.

 

I think I'm going to leave the stock line for now. I'll have it set up with AN6 everywhere after the hard-line so it will be really easy to add an AN line later.

 

I, for one, approve of this type of thinking. Although, I usually cant afford it...
