I might be confusing the two different types of pipe here. Is there a difference in the white and black pipes? When I went to Lowe's the DWV stuff they showed me was corrugated and flexible. They didn't know what I was talking about when I asked for a rigid DWV pipe, much like the white PVC, but in black.

I don't know how well the corrugated pipe would work. What I've seen has fairly thin walls, and, if the outside diameter is right for the bellows, then it might have trouble fitting into the fender hole. However, it's not that expensive, and if it looks like it might work, I say give it a try. If it fits, it will work just fine.

The white PVC pipe is Sch 40, and has fairly thick walls. Dimensionally, it is identical to the black ABS pipe that I used.

There is little or no stress on this part of the intake. You can use just about anything that gives you the "tube" effect there.

I didn't want to use the corregated stuff since it's not smooth inside and that may disrupt the air flow....and it doesn't look as good as the smooth sch 40 pipe.

There is "straight" sewer pipe that is schedule 20 PVC, usually used for septic systems. It's gonna half to 2/3s thinner than schedule 40 and much more flexible. It may be flexible enough to squeeze into the oblong shape in the inner fenders. If it couldn't be squeezed into fitting in the hole you wouldn't have enough material to shape it into fitting though.

Ya'll gotta keep in mind that these Lowes, Home Depot folks generally aren't "from the trade" so they might not be familiar with the products and/or what their intended purposes are.

FWIW, my local Lowes had the PVC test caps that AgentOrange used in his build. I used a 2" and a 1.5" test cap. Need to go back and get a 1" plug for the other hole.

I'll post a couple of pix when i get the plug but I've trimmed the rims off the caps & I'll do the same to the plug along with cutting it short so it doesn't project so far into the intake's air stream. Gives it a pretty clean look.

The guy at Lowe's told me to not screw with the intake on any vehicle "the manufacturer builds them like that for a specific reason"...after I told him what I was doing with it. I said, "Well, my reasons are different than Fords". He didn't offer much help.

[txarsoncop]

Oh yeah, I wouldn't tell them anything like that because you might end up with some hard core enviromentalist or something. I always leave it vague and tell them it's for a "project i'm doing..."

The main difference is what it is made out of. The black pipe I used is ABS and is labeled DWV on the roll stamping. PVC should work as long as the outside diameter is the same. I have not tried PVC myself, though.

Since I've been following this mod here and at F150online I can't remember which thread it was mentioned in...

DWV in ABS should be dimensionally identical to schedule 40 PVC.

DWV fittings in PVC will fit sch. 40 pipe & fittings, they're just not rated for pressure; hence their classification as Drain/Waste/Vent.

The reason some of you can't find black ABS piping is because either state, county or city codes don't allow for it. The only advantage to ABS pipe (other than being black already) is that it is cheaper than PVC. But similar to schedule 20 PVC it is not as durable as sch. 40 so many codes do not allow for it.

For the small amount of pipe/fittings being used you might as well use PVC if you can't readily find ABS and not sweat it. A little flat black paint and it'll look like ABS...

I got all of the parts today. SCH 40 PVC works with the downspout connector perfectly. If March Madness would go away, I'd have this done tonight, but it's looking more towards a tomorrow morning project.
