On the Kubota it had to small filters, one before the filter and one under the hood near the main injection pump. The way it’s plumbed I have a fuel line running from before the lift pump, near the back of the tractor up to the Racor, then from the Racor back to the lift pump, there just wasn’t another place to mount it on such a small tractor. The picture is a Racor unit and filter. A close up of it.
