Well i appreciate the parts list. Still haven't fond the adapter to go to the factory return line. also a threaded cap for the FPR would be great. Just having problems finding anything in 5/16 compression. Also I've seen reference to 3/8" line. So here's a question. If i know my check valves at the heads are 5/16" does that mean the rest of the system is?

thanks
Chad

 

You remove the check valves in the head and replace them with a 6an or 3/8" to 1/8" npt fitting.

I understand that much. I'm talking about the return line that screws onto the factory fuel regulator. that factory line just gets disconnected but will have to be connected to my new regulator. Anyone got a fitting for that and capping the factory reg?

Chad

 

You can use this to cap off the regulator on the fuel bowl. http://67.19.132.3/dieselinnovations...cts&product=25

 

That's the one I used.

 

Well my setup is a little different because I deleted the fuel bowl, but this is what I used to connect to the factory return line......http://www.jegs.com/i/Earls/361/165056/10002/-1. I just cut the end of the return line off where the flare is, removed the existing fitting on the line, installed this fitting in the link, and then screwed my return line from the regulator to the fitting. It might be a little tough to go this way with the fuel bowl still in place though. You might be able to put it further down the return line though.

Factory fuel bowl and regulator are good for more power than most here will make. That is not a problem in our trucks unless you go big oil that requires factory bowl removal. Just food for thought. My factory bowl and filter are not holding me back right now.

I used spark plug boot header shielding sleeves over my lines that feed the rear of my heads.

I may adapt my rear fed system to feed the front as well since I have no air problems in my system. It is all there, just need to mod it from a rear fed front burp/dead end to a quad feed.

 

thanks mueckster, I saw that one. Was kinda hoping for a $.50 cap, but the more I read, the more I become concerned about using something like that. Jeff that fitting is what I need, can't believe I missed it. I wonder if you could use that straight to the fitting already on the line. The fittings our fuel systems use are these Parker vibra-Lok fittings which appear to be compression fittings with fuel sleeves for the compression component. I think that ties everything together. When I get home after midnight, I'll double check all my fittings. I knew someone here would know the answer.

Thanks

The most expensive part of the DIY is the regulator. I been searching for a good price on them. I have been thinking of converting my DIY CCK to an adjustable regulated return. I like my fuel pressure where it's at with the shim, so I don't know if I really need the adjustability. Like Mike said also, I don't think my fuel system is a limiting factor with my current mods.

 

I'm with you on most of that. I do really like doing my own projects. Might take a little more time but at least I can say that I did it.

I figure my time and labor is free and I don't mind that. With building this RR kit, I actually did it quite a bit cheaper than buying the prefabbed kit. As Jeff posted, I got all my fittings from Jegs and hose (Parker push-loc 836 diesel rated) from PPE. Regulator cost the most and it was brand new from fleabay. Delete block and head fittings came from ITP. Wire loom, spark plug heat shielding, post-pump filter, and filter base all came from local shops. Put it all together based on Dennis' kit but with some changes along the way.

It's not with the mods most of us have and to be honest it's not a huge restriction at very high hp numbers either. The checkvalves, yes. But the bowl and the line size no. Cale at BTS is still running the factory SD fuel bowl on his race truck. He does have a RR kit from ITP but it's one of the first designs that Dennis had, which uses 1/4" lines. So 1/4" lines and the stock fuel bowl and he's got around 900hp!!!

I only did mine because I wanted something different. Took my bowl out because I liked having more room in the valley. That's all.


Here's the link to my webshots Reg Return album if you want to check out how I did mine:

ok, so turns out the fitting at the fuel bowl for the return and supply line is 3/8" i believe. I found a cap for that at HD and i'll o-ring it out of my viton o-ring assorment to cap the factory reg off. now time to buy some fittings and hoses.

I believe I posted up a guide of every fitting I used in mine some years ago. All of them were NPT. Check my gallery, I believe it may be in there.
