I never met a project I didn’t like
I am starting this thread a few weeks before I planned to, but the topic has come up in one of my other threads, so the timing made sense now so the topic could really get explored. In my other thread http://www.thetruckstop.us/forum/threads/going-mechanical-with-a-moose-omega-marine-ip.45204/ the topic came up when @spdgofast started planning for a large IP for his P400. I have been working on ideas for an improved fuel supply system ever since I got my Moose Omega Plus IP installed and the fuel supply system hasn't been able to provide a constant 25psi inlet pressure that my IP is calibrated for. My current fuel supply system consists of: a stock fuel sending unit with the sock removed into a filter mount with a Wix 33439 filter supplying fuel to a Raptor RP100 lift pump mounted to the frame. The fuel goes through 1/2" ID rubber hose to another fuel filter base under the hood with a Hastings FF1079 filter. The fuel then flows through -6 AN braided stainless steel hose to the IP inlet.
Here's a video of my fuel pressure under full throttle acceleration. Note that the beginning pressure wasn't even 25psi....it sometimes can't even keep up at stead-state cruising.
For about a year-and-a-half now I've been having conversations with @Ratman about a few different topics, but one of the main topics has been a fuel supply system. He has a lot of experience in fluid systems and has some great ideas on the topic. I would say that one of the main components we wanted to add to a fuel supply system was an external fuel regulator located close to the IP inlet. We also want to increase the size of the tube in the fuel sending unit from 3/8" to 1/2" to improve getting the fuel to the lift pump inlet.
I currently have my fuel system all torn apart while I am fixing rust in my Tahoe, so this is a good time to start doing some upgrades. That coupled with @spdgofast actively working on the fuel supply system for his P400 makes the timing for this thread appropriate now. I'm cross-linking this thread with my other thread so the thoughts that started over there can continue over here. I am running out of time to post right now, but will continue tomorrow. Looking forward to what ideas are come up with to get a next-level fuel supply system designed, installed and tested.
