# Service bulletin FDM\-TSB\-005

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

This bulletin provides instructions for installing a longer hydraulic hose between the auxiliary pump and the hydraulic manifold load sense port, and a straight fitting to the hydraulic manifold load sense port to reduce pressure spikes. The longer hose provides additional hydraulic fluid volume between the auxiliary pump and hydraulic manifold and acts as an accumulator for the load sense auxiliary pump function.
