I have an Idea

[Txstrmhntr]

Ok its late ive had quite  afew drinks but I get great ideas when im not very sober. No clue if they actually work or not as Im not an engineer. But here is an attached drawing I hastily drew on my computer. (Im not an artist but if you know how the system works you can get my drift)

Anyone obviously smarter than me think this may or maynot work? It would be cheaper than casting a new cam and valve cover.

Wow! We need someone that can fab this although may make the cam wear more...? But cheapest and easiest option...

One upgraded DI pump broke the F150 cam in half, just to give you an idea.
If you do figure it out (I actually thought of this back in 2013 but gave up on it) you'll have to control the spill valve, that is something I'm not aware of how to do with dual DI pumps.
There's a reason I went with aux injectors, path of least resistance and cost.

Arent fuel pumps and injectors controlled electrically?

Okay sorry forgot HPFP is needed for Direct Injection. Im an electrical engineer so mech is not my strong suite.

Would it work the same as
