My homemade vacuum tree.

[Zero Signal]

Ever since my original intake install, my vacuum lines have been a freaking mess all over the engine bay. It was due to the fact that the Explorer intake had all completely different vac lines. So I went ahead and slapped this together for less than $20 and organized/replaced ALL the lines and did away with the stock vacuum tree on the fender.

What you see it all it is: A piece of 1.5" ABS pipe, two caps and some brass fittings. I picked it up at Lowes. Right now the only line NOT there is the A/C vent control since my drill ran out of battery power before I could tap the hole for its fitting.

I wanted to make sure the vacuum was balanced so I have two 11/32" supply lines to either side of it. They are mounted in separate sides of the plenum as well. In order from left to right: supply, purge solenoid, red plastic line (spliced), driver side fender vac line, FPR, brake booster, supply

Notice the sweet dangling alarm it's fully adjustable now

I wonder if the added volume will have any negative affects If so, maybe I'll make it maller and hide it away. I was also thinking of revamping it for the purpose of redundancy and maybe run the brake booster to the plenum itself.

Anyway, just thought I'd share for no good reason.


EDIT: I may re-route the line to the canister purge solinoid to tee off of the supply line. I'm not sure that's necessary but we'll see.

Dude, watch out! There's a pipe bomb under your hood!!!

Seriously, looks good, very unique!

I'll give a 10 for originally... I can see someone bringing it to the next level....lets say something in Aluminum and polished...

 

[tmoss]

yeah, aluminun and polished Andy (watta ya waitin for)........

Put a cover on the intake!

 

[VibrantRedGT]

That's good stuff. I'll give you a 10 as well.

I thought about aluminum. If I ever get a MIG welder, I'll probably do that

I'm not gonna bother with the intake anymore since I cracked it while bolting it down. I even polished up the cover plate too

Those spacers are flange breakers............

looks great.

i was thinking about getting the stock vacuum tree and mouting it pretty much where you have it but lower. under the upper above the tranny. lots of room since the air tube is gone

post more pics man

I think that is really cool...hmmm maybe I'll try....nah...I will just get myself in trouble!!

What did you weld that with. If it was a tig than just make an aluminum one with the tig.

looks awesome, but ...

i would worry a little about what would happen to the brake booster if one of the other tubes breaks or comes off for whatever reason. the brake booster could lose vacuum and then, of course, it would be really hard to brake, not something you want then you are on the highway ...

i had mine all together at one point and my canister purge hose broke and i lost brake pressure. luckily it happened when i was in the driveway. that was when i isolated the brake booster as much as possible ...

i might also put the pcv hose closest to the vacuum source just in case oil is gets sucked in. then at least the oil might not get all over everything ...

lastly, the i'm thinking that the fpr probably should its own dedicated line so that the fuel pressure is kept as constant as possible ...

just some things to think about ...

oops, double post

Yeah I thought about the redudancy as well. The brake booster used to go straight to the manifold but I tested it out and when I disconnected one vac line, the entire manifold lost vacuum so I figured it would be uneccessary to do it that way again. BUT . . . if at some point, I decide to, I can cap off a supply line on the side and run it directly to the booster since they are both 11/32" booster lines and they're long enough. But these things aren't falling off, they are so tight, I can hardly pull them off by hand and they shouldn't be breaking anytime soon since they are all brand new and high quality. They are supposed to handle the oil and gasoline exposure. But if I ever go boosted, the hole vacuum system may need to be revamped with valves or something to prevent them from blowing apart or being forced off the fittings!

As for the PCV, it's going to the manifold. I didn't want it running to that tree at all for that exact reason. I still want to figure out a good filter system for it though.

John, I just saw this. I also give you a 10 for creativity. It's nice when someone sees the overall function of a device and knows how a system works and can come up with something ad hoc that works (and looks pretty nice IMHO. I'm not a bling guy).
