Default 1990 Ranger 4.0 V6 fuel rail

After several changes that continued to decrease a fuel leak problem, it looks like I am down to the fuel rail. Had a fuel smell on occasion for a couple years, and last Winter I found fuel pouring onto the ground one time while I had the truck warming up. It seemed like it might be coming from the regulator, so I replaced that, which eliminated it pouring on the ground, but still had the odor sometimes. When the odor was the strongest, I could see where the fuel would collect on top of the intake manifold (not predictable or frequent), and I had reused the old retainer clip from the fuel line to the regulator. I found a place with a new retainer clip, and that helped quite a bit, but I still get fuel (in a much smaller quantity) on top of the intake manifold at times. I was able to watch it collecting this last time, and it was definitely not from the connection between the fuel line to the regulator (top was dry). My current guess is a hairline crack in the fuel rail that only opens up at times.

I have called around locally and not found any 1990 Rangers in junk yards. Any idea what other vehicles or other years of Rangers would have a matching fuel rail, or other places I could call around to find a match?

Thanks in advance
