Hose barbs would b no problem.
The injector caps would have to be custom machined and SPENDY for no advantage that I could see at all.
If it changed the performance at all, it would be for the worse. We used ti pinch the return line on the old cummins to make them go, when you had about a foot of flame out of the stack, you had it pinched about right.

It is believed that the moose pump and injectors can be pushed further with larger lines. Currently the big moose injectors are bored to the diameter of the lines, bigger lines would allow the injector to be bored even more, allowing even more fuel. This is something im interested in as well. I wonder if you could take the caps off our lines and simply bore them to the OD of the larger lines... its late and im tired so im assuming im not thinking properly, that sounds way too easy.

There are larger lines out there. We use them for tractor pulling all the time, they are not 3/8". They are only slightly larger, even superstock tractors running boost over 100 psi with 4 turbos IIRC are only in the neigborhood of 1/4"

If you're thinking about increasing the size of the high pressure line running between the IP & Injectors, you'll have to be looking for some serious HP before the lines become the critical point.

she can only burn so much oil at a time.you can already roll coal by turning up the fuel,which goes unburnt out the tailpipe and gets too high EGT's as is.even with turbocharged engine.
besides that,imagine if you could somehow convert the thing to direct injection (just for starters i mean as IDI isn't possible) so it burnt enough fuel to require such a large size........you wouldn't be measuring fuel economy in miles anymore.
but i think your interested in just increasing the return lines.....still,why? is a good question.

why?
...because a couple of people who have done it advised me to so, I suppose based upon the oil being thicker. However it seems a lot of users on here don't think it is necessary. I think I'll just try the conversion without larger fuel lines and see if it works.
