Yes I had to grind some off the manifold and bolt so the manifold would tighten up flush.

Thank you

Good question. I don't know. Should I block it off? I'm trying to figure it out. Where does the rear bypass water tube connect to ? The one that goes around back of engine. Where is the PCV valve also ? Any help please? Thank you.

I am not able to screw the thermostat housing connector (pipe) into the thermostat housing, because the carbs are in the way, as seen in pic. 70-72 housing I believe. N42 head, F54 block. Any body else have this problem? Thank you very much.

Thanks, I was going to put the regulator after the carbs, on the return line.

I have the fuel rail and pressure guage in the pics. If I get a pressure guage adapter, the one you just screw the pressure guage into. The adapter also has an inlet and outlet for fuel lines. In able to get an optimal fuel pressure reading, where would you put the guage? Wouldn't it make sense to place it right before fuel rail? Before going into carbs. You wouldn't put it after the rail would you? The return line after going into carbs. I have a fuel pressure regulator in the appropriate spot. Holley UB12 or something like that. I also have an electric fuel pump fueling triple Mikunis. Any info? Thank you very much.

There is only the 2 cooling ports on the 1 carb, like in the pic. The other 2 carbs don't have ports that I see. Thank you very much.

Would this setup work for my fuel system? I have the pump and filter back at the gas tank also. Thank you very much.

thanks

There is a hole in the rear drivers side of the engine block. In the pic it is in the blue area to the right of where it says Nissan- Japan. To the right of the block plugs. It looks like their's a bolt in it, in the pic. What's that hole for? Thank you.

Thank you

I want to run my fuel line as in the pic. It shows a fuel pressure regulator and a guage. What's the difference? What does each do? I thought I knew but now I can't remember or find any info. Thank you very much.

What is meant by back pressure regulator? Is it the same as pressure regulator? Thank you.

Yes I have those hose barbs on the bottom of carbs. So the return fuel goes through them, then back to tank. How does it cool the fuel? Thank you very much.

I don't understand what your saying Tony. Could you maybe draw a picture and post it? I don't know where the cooling ports are either. I'll put the regulator in the right spot. PHH carbs. Thank you very much.
