The starter is located under the intake manifold here's a pic with the manifold removed.



To remove the starter there are 2 options remove the intake manifold or remove the transmission.

Hi, I have pasted the procedure from autozone.com below. Because this requires removal of the intake manifold, please be as sure as possible that your starter needs replacement. If you have any doubt, please let me know what your symptoms are and what troubleshooting you have done that led you to believe your starter is bad. Also, if you have any questions about the procedure below, please let me know. Thanks for using FixYa.

Perhaps you would do it like this simple scheme.

The M70 has two fuel pumps; one for each cylinder bank. One of mine died. I was able to access the fuel lines at the drivers side (US) rear of the engine. I spliced in a 10mm "Y" connector to the good pump and tied the two fuel rails together temporarily. Runs like a champ!

check for a fill cap on top of the power steering pump.
