Holley Sniper Stealth EFI - Part 6 (Throttle Body Feed Lines)

After a little trial and error, I've selected a regulator and braided fuel line for the throttle body that will be perfect for the Mustang

I originally purchased an Aeromotive 13130 regulator and Holley 534-236 braided fuel line.  I selected the Aeromotive regulator due to numerous bad reviews of the stand alone Holley regulators on the Summit website.  The Aeromotive regulator was a well built part but required a completely different fuel line configuration.  This version doesn't regulate in-line before the throttle body but afterwards which wouldn't work with the braided fuel line I purchased and would create a more cluttered appearance.  

When searching for other options, I decided on using Holley part number 534-237.  This is the exact same style braided fuel line I had before but the regulator is integrated in the line which makes for a cleaner installation.  I'd seen this one before but skipped over it due to reviews stating the regulator hit the intake or valve cover on a small block Ford.  After looking at the picture for a bit, I didn't think that would be the case and ordered the part anyway.

The part is actually a series of parts that you assemble.  The regulator bolts to the back carburetor stud to hold it securely in place.  I took a few minutes this morning to put it all together and tighten it up properly.  I think this is going to work as I need.  



I have a fuel filter to install just after the tank (left) and one to install at the throttle body (right).  The one at the tank is a Summit 220170B which has an integrated 90 degree fitting and a 100 micron filter.  The one for behind the throttle body is a Summit 230123B and is a 10 micron filter.  The plan is to put the filter at the throttle body right behind at the back of the intake.  You can see it in the picture above but I've not built a bracket yet to hold it secure.  I'll work on that in the days to come.
