Hey Bernie, do they make a 45 degree AN fitting with a male thread on one end? You could eliminate the nipple that way and maybe get some more clearance by attaching the 45 directly into the carb feed tube. Pics can be deceiving but it looks like a lot of fittings, you gotta do whatever it takes, but can you turn the first 45 a bit and attach the filter directly to it and eliminate the second 45 and unions?
A spacer will give you an inch more clearance but I think they should be used for performance reasons. Just my opinion, I'm not an expert.
Yeah It all fits under the hood, just. I'd like to have a car with a hole in the hood and a blower sticking out but I don't have a rich uncle and I didn't marry money. Sigh.
