I'm living on borrowed time with my original hump hoses. What size are they (I'm not at home right now) and does anybody have a suggestion for the cheapest/best (is that contradictory?) product/place?

 

You need approximately 2 feet of silicone coolant hose, then cut each section. I'm not exactly sure on diameter. Maybe 2 1/2". Someone else can jump in on that one. I ordered the boot/clamp kit from a vendor, and it was nothing more than exactly 2' of silicone coolant hose CUT to each size of the boot hoses. I figure if one could source this stuff locally, one might save a ton. Then reuse the oem clamps.
My disappointment in the vendor purchase was I thought I'd get boots that were designed/manufactured for my truck. But no they just took 2' of the hose and cut it to lengths. I stacked all four boots on each other and seen how they were cut. Not very good cuts either I might add.

A couple of places to get nice silicone IC hoses online.

 

Do you recommend hump hoses or just straight couplers...or does it really matter? And I think these should be 2.5"?

 

I'm not sure about the size either. You'd best measure.

Hump hoses give better flexibilty, that's what I'd use. The Cummins moves around a little.

 

sorry i know know... what are hump hoses? and what makes them different?

The size is 2.5" ID for all 4 hoses. The silicon hoses have worked well for me, 2 years with no problems.

 

WHAT?!?

After looking at my original hump hoses last night (one of which has rubbed on the frame and is worn through 2 layers!), I'm not sure if I want to go with an after market type hump hose. The hoses at the intercooler are 5" long, and the hoses at the turbo and the manifold are 4" long. All the after market examples that I've found are only 3" long. I'm not sure if that's long enough to suit me. I think I might just try getting 2' of bulk 2 1/2" hose and cutting my own to lenght. It sure is a lot cheaper than going with hump hoses!

Micaiahfied: Hump hoses are the rubber boots/hoses that connect the pressurized parts of the intake system. Our trucks have 4 of them - 2 on the intercooler, 1 at the compresser, and 1 at the intake manifold. They have a little "hump" in the middle that allows them to flex at the joint a little more than a straight hose would

Rebal: I checked out that site (and I actually ordered some intake pieces yesterday for a WannaDiesel-type smooth intake), but they don't have any size other than 4" with banded middle like the one you posted. Thanks though!
