It's not exactly what you're doing but I think it might put you closer to an answer of what type of tap to purchase.

 

You are going to want to tap for 1/4 npt and then get a 1/4npt to 6an adapter.

 

ok i will look into it

 

ok cool so 1/4 npt is like .56 inch. dont know why i didnt think of that lol brain fart thanks for the help guys

 

are you gonna eliminate the FPD? I'd love to see some pictures or a short write up of taps/fittings you use(d) as you do this. My UIM and LIM are both off atm and I've been thinking about doing the same project.

 

I am in the middle of doing alot of things to my car but as for fuel rail i am using bosch 1680 secondarys with a Fjo injector driver and stock fd 850's in the primary fuel rail and i am using a rising rate aeromotive FPR and yes i am getting rid of the FPD. I found that using aluminum tube is cheaper than steel braided and regular an fittings so i will take progress pics and make a thread on how to do step by step when i get time

 

I'm looking to do this, but I'm concerned that I won't be able to get get a fitting that clears the OMP nozzles - most people that tap the rail seem to run premix? I've got some forged 90's to try but I'm not convinced they'll clear

 

premix regardless if you have the OMP connected. if you delete the OMP just premix more... but always always always premix.

 

Sorry, I meant eliminate the OMP injectors and solely run premix.

 

We cover this in our tech how-to http://www.banzai-racing.com/pd_elimination_how-to.htm:



you can install a 45 degree 6AN fitting (i.e. Summit Racing Part #SUM-220655). This allows clearance of the rear oil injector.

 

This link works, http://www.banzai-racing.com/pd_elimination_how-to.htm punctuation always messes with links

 

I just did this last night, I happen to use a 90 degree -6an fitting to push loc hose -6an type of 3/8 is the same size, the 90 degree clear oil injectors but if u keep your rats nest u will have to slightly bend it towards to the tranny side, but it work.

ok so this is weird. i tapped my primary fuel rail for 1/4- 18 npt and it was so freaking tight screwing it in that it actually broke the primary fuel rail and put a crack in it. im thinking that the tap is faulty or something
