    When I order them from Rock Auto using those part numbers, they always come with the compression fittings.

    Yeah, I got these parts yesterday. They come with the compression fittings. I'm not planning to use them myself, but they're there.

    Help me out guys... I got the saginaw fittings I thought I needed and tore into things today. I removed the AN adapter that was there before, and the hole it was threaded into is not even close to what I was expecting. The thing on the left is what I pulled out, the adapter on the right is what I intended to install. What's going on? Did someone butcher the throttle body? This is a major drag because I dropped $40 on a fuel pressure adapter in the GM-saginaw style...

    Wow! They must have drilled the pod for NPT fittings. I'll ship out an injector pod to you tomorrow morning.

    Thanks! I appreciate the fast shipping on those adapters too.

    It's sad how many hours of my life that customEFIs guy has stolen. Literally years of frustration.

    I can understand. I was one of several guys that were unknowingly providing technical support and tuning advise for him. When he was called out, he really thought that selling a calibration then telling the customer to ask for help on a public mailing list instead of standing behind it was just fine. Hopefully you're finding the help here to get this ironed out.

    I actually understood well enough how to do basic tuning, but since he gave me 305 injectors instead of 350, we were going around and around about why the initial tune was so far off. Figuring that out was a huge breakthrough, but there was something wrong with the ECM too. Everything came together when I bought an ECM from DynamicEFI. Hopefully this is the last time his legacy will burn me...

    Got it mostly put together today. Front routed fuel using factory lines. Still need to leak test and all that, but it should be okay. Thanks everyone for the help and ideas.
