Hi, I'm trying to decide between paying $384 for a Cat manifold or a $230 manifold on eBay. It's for a Cat 311B 8GR00134. The picture looks right, but it does seem to have an extra test port coming off one of the cylinders. Anyone have any experience with discount manifolds? https://www.ebay.com/itm/S4KT-3064-...132281147868?_trksid=p2385738.m4383.l4275.c10
The difference is only worth 1 hour's labor. I wouldn't do it.
