I did a small piece of hoes than a 90* and down along the rail.Diesel rated fuel line works.
As far as running the CCV into the exhaust, I cut it in after the muffler using the parts from the same Moroso kit. However, I did develop a really bad blowby problem after awhile. Don't know if it is related to the CCV setup or not. I did loop the hose over the power brake booster which may not be a good idea. The rubber in the anti-backfire valve does harden up after a while effectively sealing off the CCV. If you choose to do the exhaust setup, definitely don't use the valve, just use a hose nipple/NPT fitting instead.
Your street/race car exhaust has pulses that why the header evac system works. A turbocharged exhaust system is "pressurized".i ran mine open for 2 years and decided to run mine into the exaust I did it with a one way check valve welded in after muffler in tailpipe angled to the back of exhaust. Brand new engine new everything and no blow by and in less than 2 weeks i had leaks everywhere and actually blew out the seals on my new terminator twin oil pump to a tune of 6 quarts in 100 miles. I have had a street/race car with a moroso system that scavenged the pcv into the headers and it worked great. I dont know what was wrong on the diesel system I had read where others had tried it with good and bad results from different people and thought I would do it. All I can say is Dont Do It. I think SUN posted the same info build a catch can under the truck and be done.
