I found a few -4AN fitting adapters but I need to know the thread pitch.... Majestic has number 26 listed as M12, but is it M12 by 1.5 or M12 by 1.25?

Ask Stan at fast-turbo.com.

 

I was going to run a gauge on the fuel filter banjo bolt and then run the nitrous feed line from the rail. But now that I think about it, I might just look for a 1/8 brass tee with 1 male on the side and two females on the middle and side. Then just throw a 1/8 to -4AN on the tee.

 

Don't use a B&M gauge Use something liquid filled if you don't have one yet

 

Just purchased a Marshall liquid filled shock proof. I did my research.

 

I have the same gauge but I removed the top plug on the rail fitting and tapped it to 1/8 npt.

 

^^ Sweet. Some DIY goodness. I love it.

I was planning on using the same type of fitting on the fuel filter banjo bolt so I could use that extra port for a nitrous fuel line.
