## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked great!
*by J***G on July 11, 2024*

This worked as a replacement for my 2005 Volvo Penta 8.1Gi-F. These are used for the risers on top of the exhaust manifolds where they meet the Y-pipe.A helpful tip for installation is to first remove the riser (make sure to have a gasket kit on hand). Also, mark the position of the old bellow to ensure the new one is positioned correctly. Use a screwdriver or a similar tool to pry around and break the seal of the old rubber. To install the new ones, apply dish soap on the inside for easier insertion. Push them into the Y-pipe, then into the riser side, and bolt the riser back down. It's essential to use dual hose clamps for a secure fit.If you find a leak you might have to reposition the bellow or ensure all the hose clamps are tight.

### ⭐⭐⭐⭐⭐ Good  quality  parts
*by D***F on October 15, 2019*

Just what I needed

### ⭐⭐⭐⭐ Arrived just as advertised and worked ok
*by N***7 on August 16, 2022*

These hoses fix almost as good as the OE part that they replaced, they were a little shorter (about 3/8”) so I had to do a little extra work to get both clamps over each end of the hoses and sealing ok. Otherwise the diameter was spot on and the rubber was of good quality.
