Instructions for mounting replacement fuel pump # 8556 on V4 crossflow motors:

It mounts on the manifold as illustrated above.

You will need a couple of 10-24 stainless screws to mount it. These are generally available at a good hardware store but typically come in either 2" or 1-1/2" lengths.

On some motors these may bottom out; cut them to 1-3/4" if this happens or shim the screw heads with something). 1-1/2" are usually are too short.

You will need to plug the VRO pulse hose source (on the block for most motors *). These take a brass or SS 1/8" pipe plug.

The oil/fuel mix in the fuel tank will need to be 50:1

* NOTE: on some early (1984-86) motors the pulse hose fitting was installed in place of the plug on the manifold as above, rather than on the block.
Remove that and install pump as otherwise directed.

There will be nothing to plug at the block.
