Yes, re-read that write up. You want to drill off center into one of the exhaust passages. Preferably the rear one. If you drill the center, you are drilling all metal.

What you are thinking of is the tap, you only want to go as far as the fitting that you have, this way you can tighten the fitting up and not have it come out.

Ok, ill reread it. So i can drill all the way just dont tap all the way. Now, i just bumped my starter and im at 13.5 psi on my fuel pressure gauge with only a pump in the tank but shouldn't that have been enough psi to sufficiently feed the vp? I dont know what idle or wot is because it doesnt run right now

When drilling the manifold, you only have to go through 1 side, not both.

Now for the fuel pressure, 13.5 is enough for idle, not WOT. For mine, I am running about 18psi at idle and 14 psi at 75 mph, or 2200 RPM. This is enough to open the overflow/over pressure valve that returns fuel back to the tank. Also, try to not get below 1/4 tank, as the fuel gets less and less, there is the probability of heat build up in the fuel causing the VP-44 to overheat and fail.

makes sense. One more dumb question. As far as "water hammer", do I need to be concerned with that for the hobbs sensor as well or just gauges. Im asking becuase Im thinking if I get a "T" i should plug the bottom part of the "T" into the hole and use the top for the gauge and hobbs. Otherwise only one or the other will be protected from the water hammer effect.

If you are using a grease gun hose, and have it turned 180*,the water hammer effect is minimal. Also if you put the hobbs switch and pressure sensor across from each other, it will be better off.

That's what i planned to do but i figured if i used a T with the bottom part in the truck and the gauge and the hobbs opposite each other i wouldn't need the grease gun hose because the 90 took care of that. Do i still need the grease gun hose regardless?

Yes, the water hammer will still get to them. With the hose, you will reduce the water hammer effect with the bend in the hose.
