You plan on running the 3/8 from the tank to the pump? How much do you think it'll take? And which will you use to get a larger ID? Seriously, since you started that thread, evertime I start my truck I go over to the passenger fender well and listen to the "cackle". It drives me nuts now. But the regulated return thing is over my head. I've been reading and reading but it intimidates me.

Stage I-done, replaced tank to pump hose fittings/hose
Tonight i did my hose run from the tank to the suction/inlet side of the uplift
fuel pump. Pretty easy except for trying to get in to the tank fitting. Used my
special 3/8" quick release wrench and a pair of pliers to smoothly pull the line of
the tank. Took Kwik's advice and put two hose clamps mounted 180 degrees
from each other and in opposite directions on each end.
The 3/8" is inner dia. hose measurement, cheap hose($1.20/ft.),multi fuel line
i got from IHC. Used 6' 6" length on my truck(short bed) tank to pump.

Update
Just finished my fuel delivery system(engine side) mod yesterday. Took it
out for a short drive and ...WOW!.. nice quieter operation. Idle is noticeable
and 65-75mph cruise is quieter.
I'm amazed at how small those inline check valves are for each cylinder head.
I measured 4mm ID(1/8" NPT) on outlet side and the inlet has a mesh screen.
Glad they're gone! Replaced with -6AN(nominal 3/8") SS braided line and fittings.
Can u say max flow!
Minimally i would go in and replace the feed line and remove those dang valves...cheap fix.
My reg return system total cost:$350.

Quite the project! I'm just about ready to power up the fuel pump yea know...
check,double check all fittings for tightness, replace fuel filter(pretty brown!)...
here goes...pressure building...air escaping thru reg...then....splash!!!....shower
from LOOSE fuel filter cover
. Now i have a real clean motor compliments of #2 diesel fuel washing. Diesel fumes in the house really suck!

Another question on this subject. I was planning on gathering the parts to do a regulated return but Kwik's method also very interesting. I'm trying to reason out what may be the 'better' system and why. It seems like both the regulated return and the orifice method gets rid of the air in the system, but Kwik's method looks less expensive. Can I get some insight on the technicals?
Thanks............

Kwik's design is effective and cheap...probably less than $75.
My design allows enough head room to grow into down the road if i want to upgrade to bigger injectors. I used SS braided line(racing stuff for any fuel)
-6AN size(nominal 3/8" ID) with 350F heat handling and real high pressure. Looks REAL nice...doesn't rust. I got the swivel fittings making it easier to run line and set up in the tight valley space. The external reg gives precise control of FP.
I'll have some pictures for everyone soon.
