Fuel line restrictors
Looking over some old threads on different things that have been done, I can across one on removing the restrictor fittings and putting ones in that are open. This sounds good to me but it begs the question of why they were in there in the first place? I'm sure somebody in design thought they were needed for some reason. What problems could come up by taking them out?

Thanks for the reply, I've been traveling and just got on to check. If a person removes the checks does it cause any problems with starting or pump function/longevity? If a person does the CCK the pressure would bleed thru the orfice anyway right so would the regulated return work better or not?

Actually another thing that they do is isolate the pressure waves inside the heads. When each injector fires, it accepts more fuel, in turn making a pressure wave. If this isn't isolated it theoretically can damage an external diaphragm regulator, and even the fuel pump. Never heard of it happening though. Shouldn't be a problem removing them.

Is there a number of people out there that have removed them and how long have they been out? Any problems? This really looks like something I'll like to remove but I hate going against design unless its been proven to work and give benefit.

I removed mine when I installed a new fuel system with bowl delete. Just let your fuel pump rum a few seconds before cranking truck while the WTS light is on, 3-5 seconds is all it takes to build the pressure.
