For all out purposes I don't use the 1/8npt ports - I feed the end of the rail directly with -6 hose using a fitting similar to what David sells. But then again for all out purposes I don't use an electric fuel pump either.
I have access to -6 JIC fittings with adaptation to 1/8", 1/4", 3/8", 1/2" NPT pipe. Its just a matter of getting it to fit in the head?
Its just interesting that you have an eighth inch hole feeding 222 cubic inches.
Can it be easily oversized? To maybe 1/4" fittings? Or 3/8"? -6 JIC is what the hoses are on mine, apparently a slightly different connection style than -AN? But still a "3/8" line fitting.
I've got the intake spider off of her and soforth right now, and was just curious if it could be done in-truck and safely...
Only doing 160cc single's for now, but I am trying to uprate the fuel system, pump-forward in case we get the B-code itch later on or something heh

Hmm.
Well, not nothing.
I'm not an idiot. What did you think I thought was going through a FUEL inlet? Magical pixie dust?
Point being my 2.2L 4-cylinder has a larger fuel supply. Our 1.9L TDI has a larger supply. Our lawn mower has an eighth inch carb inlet.
I am not an engineer specializing in fluid dynamics. If 1/8" works well, awesome. But I have enough reason to wonder and therefore ask. If I'm wrong, ain't the first time.
If you are monitoring your fuel pressure (and maintaining your desired pressure) on the outlet of heads to the regulator, then you have plenty of flow for your application.
IIRC, the only check valve is right where the stock, hard fuel line goes into the back of the passenger side head, and the front of the drivers side head. And it comes out with a 9/16" wrench.
I haven't drilled crap on the fuel systems I've done. :shrug:
maybe its not a check valve..when the fuel goes in the head though the top..it goes though a fitting to change direction..to get to this you need to go though the big plug at the end of the rail....i wish i could remeber what the he%& its called...but from what i hear..its just under an 1/8..i think some guy's like the fitting for the big plug do to that little restriction...im not looking for big HP..ill be happy at at 500-550..so if its not being done by most..i wont worry about it..but seen how the motor will be out..it would be time to do it..
Then I was wrong lol. Chock down time number 4 billion and.... heh
