Nope. Don't push your luck. SAE30R9 5/16" multi fuel is your best bet.

Nut, did you gut the stock regulator or just cap it off? I found the right cap yesterday at Home Depot, 3/8" cap for a compression fitting.

 

Nut,
I have been looking at Kwik's air bleed system, but am considering using an external regulator set-up like to one you have put together. Where did you get your regulator and about what did it cost? Also, how is this plumbed compared to Kwik's system? Thanks!

 

Hink, have you read this whole thread, from the first post? I think you'll find most of the information throught the thread. But in short, nut's system is fed from the rear of the heads, out to a regulator through the front of the heads, then back to the factory return line. I think he just capped the stock FRP on the fuel bowl. Not sure what regulator he used though. His cost = $350.

 

I am also doing a regulated return system, I got a regulator off of ebay from speedindex for about $36.00 shipped to my door. It is a nice machined part and looks like it will do the job, we will see. Like this one.

No gut just cap.

Cool Thanks Nut

 

Regulator: Kirban Performance-(#5107)$125 shipped to the door.http://www.kirbanperformance.com/

Plumbed like DI's setup : http://www.dieselinnovations.com/techfiles/reg-kit.pdf
Good diagram and parts list with hose lengths ..Caution: some irregularities in the instructions...i can help u thru it.

I don't know a lot about different brands of regulators, so please enlighten me, Nut. Why the Kirban and not something different like Aeromotive?

 

Looked around and found it to be a good price. It's billet and looks real nice.
On Kwik's original post on the fuel delivery air bleed someone mentioned Kirban
and had good things to say. They gave part # and web site i believe...nice and
easy. The wife and i are fighting over time on the computer now....i'm rigging up a laptop to solve that problem. Needless to say i can't do lots of shopping.

Thanks for the help! I checked quick for diagram over at DI, didn't see it. Exactly what I needed, still trying to decide if I want to use a regulator or not. I was a bit lost looking for one, so thanks for the link. I've learned a lot here, still have much more to learn though. This is certainly the place to do it, you guys are a big help!

 

Nut,
Think I'm going your route using the DI's diagram and the Kirban regulator. DI's instructions say to remove ac compressor, did you have to do that and if so do the lines allow enough flex so you don't have to disconnect them and mess with refrigerant? Also, did you use a pressure gauge on the regulator, I noticed there wasn't one in your pics? I saw Kirban has one that attaches directly to the fuel pressure service port. Thanks again for your help!

 

Sorry Nut, couple more questions. What fittings did you use to connect to the vibra lock connection at the factory return line? Did you use the same ss braided hose or regular fuel line? Thanks!

 

You don't have to remove the AC pump. Let us know how it goes hink10.

 

KWik said it...don't have to remove Ac pump...just swivel out of the way. No pressure gauge mount on this regulator...use the spare port on the fuel filter bowl. I''l get more pictures posted tonight.
