Fuel line sizes?

[PGreenSVT]

Anybody know what size the feed line to the engine mounted filter can is? Is it 3/8? How about the lines from the can to the front banjo bolts?

Just went out and measured with a 1" micrometer. I could only reach the feed return line and the fuel feed line going to the pass side front head.
Feed return line-- .368" almost 3/8" O.D.
Feed line to front pass side head--- .251" just over 1/4" O.D.

I know you want to retain some of the stock fuel lines, but here a write up that Garrett did over at DTT. He used all aftermarket lines and blocks, I'm not sure how he's regulating the psi with the AD1.

Thanks Lilpooh.

I checked out the link to Garrett's setup and I have to say that guy is goofy. There was absolutely nothing to be gained by the 2 extra Y blocks and running fuel lines to all 4 ports on the heads. It is still a dead headed system with fuel pressure coming in the front and back of the heads. He could have achieved the same thing with 1 -8 to -6 Y block, feed to the -8 and lines from the -6's to the heads. That would be functionally equivalent to the mess he concocted. I guess when you have access to free stuff you use all you can.
