PS:
Check your head. Some models have a plug oposite the oil gallery to the rocker arm assembly. You might be able to re-size this to work.
Looking back I think the large truck filters mounted on the firewall & that is where their sender was.
It might be possible to put one on the front by the timing cover @ the end of the main oil gallery.
My engine is covered in the shop & I didn't get time to 'dig it out'. Perhaps this weekend.
