stick with the ones hes got. theres no head heads like your turbo setup and it will perform better. and the 7.3l wont flow more then the 6.9l so the hose size isnt an issue.

im with riotwarrior is there a set made for the 7.3 yet? i know they have a larger diameter hole and when i turn the pump turned up and put my turbo on i'll want a set with the larger hole. i know this debate went on earlier in this thread i think.
Plus when I add a HiPo pump, I want to be sure there are no problems!
Dad landed a $10k job with a tight deadline when he was out here looking for a house. His current employer subs work out to him on the side. He's a bit tied up with that right now, but we discussed the larger diameter barb setups.
I don't understand why Ford went with a larger diameter return barb setup between the caps. There isn't any pressure to speak of. It's almost like they changed it to get different parts out there for their customers to buy.

1. Planning for increase in power, flow from fuel pump.
2. and this is more n likely it, larger diameter tubes have more sealing area and less chance of or longer time between leaking air into system.

Again, I cannot prove this I just feel that there is better bite with the larger 7.3 caps for the return line and less likely to leak. I'll be patiently waiting for your 7.3 caps, especially the Turbo style I need.

It wouldn't be the first time a major car maker changed something just so they could sell you a new one.

I would like a set but It will have to wait until the wallet gets a little thicker
Now I have no proof of this though it's my thought on the larger barb and changed fittings.

High Flow um what? What Injection pump will you be using that is returning more fuel than mine or another? The injection pump meters an amount of fuel to the injector, anything not used will be floated through the return lines under no pressure at all or just a tiny bit so you could run 200 psi at the IP and it will only meter a set amount of fuel that you cant change, you might mess the timing up but not the return lines. A super moose pump maybe if used with stock injectors will be more but what are you referring to exactly? this HiPo?

hey, relax, i didnt ask you to debate. I just wanted to know if you were planning to put a high pressure fuel pump on your ride and i was going to warn you in doing so, it will mess with the timing. really doubt a moose pump if used with the correct injectors, not some redneck job, would have any more flow over stock in the return system. but if you know something feel free to share.

I know nothing....and plan to keep it that way.....hear see speak....lol
Just want the larger barbed fittings if I can get em, why...cause I do! Nuff said, same reason my truck is likely a different colour than yours. Cause I like my truck a particular way.

Not that I want to jump in the middle of this . But My reasons for the 7.3 with the larger return lines is that I will be running a AIRDOGII for my fuel pump regulated down to proper pressure for the MOOSE Products that are going to be Used. I have been in other trucks running MOOSE Pumps and fuel pressure drops off real fast when leaning on that little pedal. Cannot tell you if it is going to make a big difference but it makes me feel better
