Unaffordable nightmare? Merely making the caps stationary would solve about 90% of return line leaks.
My caps seal, right until the cap gets moved, then they leak. A different designed cap, that seals with crush washers on the existing shelves on the injector, tensioned by the fuel line would IMO eliminate the problems with the return lines.
Otherwise, you could just add a spacer to the top so the fuel line holds the cap stationary.
I do not believe the problem is the cap's quality as much as those dang things move all over everywhere. These o-rings aren't meant to seal moving objects. They aren't a shaft seal.
The reasoning behind the manifold is. (If it is in fact the caps moving all over the place that is causing the leaks) a 1 piece manifold will mitigate that movement in which case they SHOULD take MUCH longer to go bad. IE By the time one goes bad just replace them all. and you also never have all those caps and fuel lines and clamps to replace again. Also If you pull a cap for a oring replacement then you essentially disturb the caps to either side when removing the hose. I love the idea of aluminum caps and I think they would be a huge improvement. The manifold idea came about as a product of listening to the problems people are having and trying to come up with the most reliable cost effective way to fix the problem. Like I said I'm just thinking out loud.
