Brief Description: fuel system planning
|
|
I sketched up the firewall-forward part of the fuel system about a month ago. It's a good thing I did this before getting too far into its construction, because I began to see problems. Since the engine has no internal fuel pump, I had to add another el;ectronic pump. That meant another fuel filter, and, to prevent the fuel from flowing backwards, a pair of check valves. The output of the check valves needed to go to the carby, the primer, and the fuel pressure measurement device. It was getting really messy.
I couldn't do much about the input, but it looked like the output could be cleaned up by creating a manifold. I discussed the idea with my son, whoo concurred with the general idea. I created the sketch (Image 2) of the potential approach. He'll look at it, and make any changes he needs. Meanwhile, I inventoried parts on hand, and ordered missing pieces.
