WHAT FITTINGS TO USE? Custom Fuel Rail w/ Stock Injectors

Hey, all!

I started a fuel injection upgrade years ago and am finally working on it again. I have a custom, home-made fuel rail VERY similar to the PALLNET rail. I am using stock injectors, the stock pump and an Aeromotive A1000-6 regulator. The rail is tapped with 3/8 NPT holes. What is the best fitting(s) to use to get from the 3/8 NPT to the stock, barb injectors? What is the size of the fitting on the hose-barb side? Do I go from 3/8 NPT to -6 AN to barb? Any help would be greatly appreciated!

Why don't you use a 3/8" NPT to 5/16" hose barb? The short piece of hose that comes on a stock injector will fit a 5/16" hose barb.

Googled and found this for example but you can get them at any hardware store - http://www.boydwelding.com/products/parts/brass-38-npt-to-516-hose-barb/

I already had 45 degree NPT to -6 AN fittings on the rail. I couldn't find a decently priced 45 degree NPT to 5/16 hose barb adapter. I finally found a -6 AN to 5/16 Hose Barb adapter. Jegs and Summit don't carry them! I even called the support team and they couldn't find it! Finally found them here: http://www.jayracing.com/index.php?main_page=product_info&cPath=2_12&products_id=320
