What are the pro's and con's of adding a regulated return on a early 99 F350.
It has a DP tuner, 350 HP south bend clutch 4 inch down pipe and exhaust 6637 filter,Cross over line, 6 speed and gauges

constant fuel pressure to the injectors. you use your pumps full pressure into the heads and then what doesnt get used hits the regulator. Its a good thing to do plus you can do a fuel bowl delete at the same time if you want to put some filters down on your frame rail

a regulated return benefits any 7.3 psd. it prevents the #8 injector starvation which leads to a smoother running, less noisy, more power engine and a longer injector life. plus you can raise the fuel pressure which will make it run better. the only con that i see is the cost....

I have it on my truck and it smoothed out the idle considerably.
