I can’t find 8” to 7” rubber reducer

[Scott & Heather]

So I'm rerouting my intake system in prep for my rebuilt turbo which hopefully will arrive late this week. I need literally one thing. A rubber 8"-7" reducer coupling. Anyone know where I can buy on of these? I've looked extensively on the internet and no dice. Truck pipes doesn't carry them either.

Donaldson P112609
Heavy Duty Manufacturing  35-87

Not that I have one in stock nor easy to get it to you but at least you have a part#.

www.intakehose.com has it for $31.73 you can probably beat their price but their hose will be new not something that been setting around for 20 years like the Ebay crap

An alternate option is to pick up a spacer that would fit in one end of an 8-8 hump hose and would be 7"ID to fit you tube. ONLY as an alternative.

Juicy! Thanks gents. I had no idea what the official name of these were. I will look through these suggestions and make an order today. In other news, apparently the ecolite filters aren't bidirectional...photo of my collapsed filter to soon follow.

Be careful that water can't get into it. Several hours of running in the rain can injest enough moisture into one to cause degradation in some elements.

Only the Eco or EcoLite with the cone shape filter inside is not bidirectional,most all ECO filters have a water proof media wrapped in a plastic netting and water drains,check the CFM rating

are you saying the filter flow killed your turbo ?
or dusted your engine ?

[Scott & Heather]

I don't think either. It wasn't completely collapsed just starting to. But yes it was wet because of where the intake was located. I'll be changing that around.

Scott. Where are you routing your turbo intake?

good.
you do know that adding radius's needs calculation ? how different is your new install ?

Ok, since this is dragging into a longer conversation:

Last year in an effort to make room for other stuff and clean up the engine bay, I routed my intake via a short straight tubing section into my ecolite filter in the curbside of the bay. The problem is that the filter intake was pulling water spray and leaves etc from the pavement since it was sucking air from basically near the floor of the engine bay side door area. I'm now reinstalling the original factory intake tubing which u turns the intake to the drivers side and then sucks from the twin plastic tubes running to the bed room wall and sucking in air through a side inlet near the roof of the coach. That's factory so I'm basically returning it to factory but using an ecolite filter instead. It's 1900 cfm btw.
