N20Silverado, ok dude, just and ! You are providing no help, just bumping those gums of yours. I'm not gonna stoop to your level to have this little keyboard war with you. Its gay, like you. I gotta get back to pushing my broom. ...and by the way, if you're such a smarty pants, why the hell would I put it on a cnc anyway and make a program for it? I was making a statement saying that I had access to many machines including cncs. You can run cncs manually einstein.

Why in the hell would you program anything? It took me about 4 minutes on a lathe to turn mine down.

Phil99vette, damn, you've got remote everything, lol.

Just curious from looking at Phil99vette's pic, do I necessarily have to pull the vacuum off the valve covers or can it be pulled from the valley cover? If so, then I could cut down that nipple, fill it in with weld, then weld a bung on it.

You can pull it off of either the valve covers or the valley cover. My old setup was off the valve cover and it got alot of oil in there because of the short valve cover height and the amount of oil that goes to the rockers. I switched over to the valley cover with a 1/2 aluminum tube baffle to eliminate picking up the oil like my old one did. I probably had 1" after 6 passes. Where do you want to pull it from? Intake choice has alot to do with where you can do it. If your using an LS6 or similar EFI intake your going to pull it from the valve covers and use baffles. Single plane you can go to the valley.

Speaking of fuel lines, how do you plan on routing your fuel line up at the engine?
Mine will run up the driver side frame rail.

Phil99vette, I'm guessing you took it the wrong way too. All I was trying to tell you guys is that I work at big oil company, in the machine shop (not as a broom pusher as someone seems to think) and I have access to several machines including CNCs. I never said I was going to put it on a CNC and I never said that I would make a program for it. I'm not making multiple parts.

Setup is what takes time, not the machining. I can take care of whatever machining is needed. The douche bag above is just trying to stir **** up.

I'm running a Beck sheet metal intake and GMPP valve covers. I had planned on capping everything, installing my factory fill cap, and welding a bung on the valve cover. But now that I saw your setup, I think the valley cover may be a better choice for me. There's definitely room there at the valley because my intake sits off quite a bit.

I'm sure your fuel lines will run along the driver frame rail, but I was wondering how you planned on plumbing it in/around the engine area, particularly fuel rails.

I just need to figure out what I'm going to weld on the valley cover. Do they make female AN bungs? If so, then I can keep everything 12 AN having a male end at the end of the vacuum hose, threading into the bung off the valley cover.

.

They make female, several companies do, I have several, work great. They have a tall model & a shorter model. I prefer the shorter one.

Phil's car is amazing, you can't go wrong comping his idea's or set up.

I'm taking mine of the valve cover but i'm running a carbstyle intake too, i've got plenty of room around it for bungs.

I know the -16 is huge, i'll be running a -2 to the pump to a -12/-10 y block and -10 to the rails and regulator.

Dragaholic,
just about every fitting company makes weldable female AN bungs.

I'd run it off the valley cover. Less chance for oil to get into the vacuum pump.

I'm going to try and keep it out of the engine bay as possible. Its going to shoot in from the driver wheel so its out of the heat as long as possible.

Summit has -12 bungs for about $5, I got all of my -10,-12 and -16 from them.

Just make sure you do a good job using baffles. Mine sucked some serious oil in my NA motor when I was on the brakes.

Alright, I thought you were seeing it the way he did and wanted to clear things up.

I'll probably end up doing it off the valley cover anyway. I didn't realize that it could be done there. Will it be just as good?

Where do you plan on putting your regulator and pressure gauge?

Lastly, these baffles you speak of. Where do they come into play at? I'm totally lost on this.

And for anyone who wants to answer this, how is the pump lubricated? I thought you wanted to suck in a little oil from the engine so that the pump is lubricated?

Depending on how thick the valley cover is and what kind of room there is, you might even be able to use a bulkhead fitting on there, just drill/tap the plate and thread a bulkhead fitting on there and then run an elbow to get the line headed off to where you need it to go.

I don't even know what a bulkhead fitting is. Will that hook up to an AN fitting?

these pumps are insanely powerful, they will suck in oil mist that is generated during normal operation.

baffles are inside the valve covers to keep oil from getting sprayed out of an opening.

Are you talking about the fuel pressure gauge and FPR? if so most FPR's come with a small port on the front to mount the gauge, that is your best best.

a bulkhead fitting is a fitting that can be threaded into metal/plastic/etc and uses a jam nut to keep it from backing out. they are used so not to run a hose through a grommet its a safer connection.

i've never looked for a -12 bulkhead fitting but im guessing it would be incredibly expensive.

This is what I want to use, does it matter if its female or male?

I think the valley is better because its a better shot at getting to the crank case vs going on one bank of the engine.

Where do you plan on putting your regulator and pressure gauge?
This is probably a dumb question but for the fuel system or vacuum pump?

Lastly, these baffles you speak of. Where do they come into play at? I'm totally lost on this.
Baffles will reduce how much oil the system picks up. Basically I'm going to use 1/2 of an aluminum tube under the valley cover so it reduces the chance it picks up oil.

And for anyone who wants to answer this, how is the pump lubricated? I thought you wanted to suck in a little oil from the engine so that the pump is lubricated?
The pumps run dry. Basically they have a cylinder on the inside with an offset mandrel with slots in it. The slots have graphite wipers that slide out as it rotates creating a vacuum. The design is soo **** simple it makes me sick. Its like a sideways fan.

I'll look at mine when I get home. I'm thinking we need to see how much clearance you have between the top of the rockers and the valve cover. Maybe 1/4 of an aluminum tube running on the inside of the valve cover with small breather holes on the bottom so it avoids the oil spray.
