Fuel Pressure Regulator Fitting Size?

[Bolesk6528]

Hello, I just wanted to pop by and ask a quick question.

I purchased a Kirban Fuel pressure regulator for a Buick to work with my Stealth Ram Intake on my Camaro.

I quickly noticed I have no idea what size thread it is and for the life of me cannot find a definitive answer online.

I was told that it is the same size thread as stock, I would really appreciate it if someone can give me an answer.

Thanks in advance!

The stock return on GN/T is saginaw, oring, 14mmx1.5 The feed is 16x1.5 IIRC, been a few years. They make adapters to AN, but run out of room quick on a stock GN/T setup.

THIS is exactly what I need, thank you so much.

On my Camaro it will run out of room VERY quick, I would need a 90* version of the fitting, but not sure anyone will even make one.

I haven't bought this myself, but Racetronix sells a Fragola fitting for the FPR return that has been machined for higher flow. It also uses and external o-ring washer rather than the internal o-ring that you usually see.

The FPR fitting is 14mm x 1.5 to -06AN, item code 392-460614BLM: http://www.racetronix.biz/itemdesc.asp?ic=392-460614BLM&eq=&Tp=

The also sell the 16mm x 1.5 to -08AN for the fuel rail feed connection on turbo buicks, item code 392-460816BLM: http://www.racetronix.biz/itemdesc.asp?ic=392-460816BLM&eq=&Tp=

Will this work? After looking at my setup I absolutely have to have a 90 coming out of the FPR before it starts hitting things.

I believe so. That is the same fitting they used in this article: http://buickturboregal.com/install-6-braided-return-line-buick-grand-national.html.

I have seen the regulator turned upside down on the stock fuel rail and the AN adapter for the return run of the the top. Looked crazy but it did work.
