6.0 regulated return?

Dad has an 03 6.0 woth 52k on it that has had one injector go bad so far and at the time, dad just replaced them all with the stock ford injectors cuz he figured if 1 went the rest weren't far behind. Regulated return fuel systems is raved about for the 7.3's.

My question is, does a regulated return help a 6.0 much? Dad isn't much into getting big power out of his 6.0 but would like to make it more reliable even though it really hasn't been bad at all so far. Would 05 and up heads and intake manifold help any? I know egr delete is a good thing. Does a more free flowing exhaust help? Any small injectors that are more reliable than fords?

His truck is completely stock all the way down to the original tires with 52k miles on them. Truck is an automatic crew cab shortbed 4x4

Thanks

Re: 6.0 regulated return?

I say get a air dog II fuel pump it will replace the stocker on the frame drill the banjo bolts and call it a day the air dog filters fuel better and the high pressure pump will keep those rails full of fuel so u dont waste injectors!!!And i would do a egr delete first thing...

Now if you want to do it cheap just get a regulator spring and drill out the banjo bolts heres a link banjo bolts - Powerstroke Nation

I like the air dog idea because of the filtration and water separator i like mine so far...

Re: 6.0 regulated return?

ok the banjo bolts are bolts that have holes on them allowing fuel to get to the heads. Drill them out and take out the spring inside them and they flow better. Also you do not need a regulated return kit or bigger lines until you go over 190-200cc injectors a simple upgraded fuel pump is all that is need up til that.

airdog 2 and fass pumps are internally regulated. no need to add a second.

Re: 6.0 regulated return?

Unless you are of the opinion that regulating the pressure 10' before the demand is the wrong way to go. Using the AirDog/FASS regulator for system pressure places the regulator before ALL of the sources of pressure drop (hoses, fittings, fuel rails, injectors, etc)...rather than after. Not how I would do it...

While the AirDog and FASS are great products, they don't address the deadhead rails, small fuel lines, etc.

But a truck will still make about 700hp with the stock lines and stock banjo bolts in it... The rail goes past the injector. The orifice to the injector is .060 which is fed by a rail more than 4 times that. The pump will send enough fuel to drain even our big fuel tanks in anywhere from 30 mintes to around 12 minutes.

Last time I checked the pump sends the air through the return off the fass or the AD. Then the regulator up on the engine still returns fuel back to the motor as well which is around like 20 inches from the passenger head. We don't have a need for long lead injectors on 6.0L our head and injector works much better.

Come on now...

Re: 6.0 regulated return?

Since all the conversations I've had with people that build 6.0L injectors must be meaningless, the warranty terms of some 6.0L injectors are certainly meaningless and of course...the experiences of my customer are meaningless...I'll just say this:

Whatever floats your boat.

Not in the mood to argue tonight.

Is it really a good idea to bring up the stellar reputation of injector builders reliability vs OEM.

Ford had to mark the factory filter to point out that people were too lazy to even change filters on time and give the dealer a way to hand them a "here's your sign stupid".

My boat floats very well. Back it up with some data and lets postpone the discussion when the mood fits.
