Dumb question, I know that CAT produced the above gauge to give a more sensitive scale for oil pressure range on the D315, I know there was a service bulletin out about it. So I thought I'd be clever and put one on my D4400 powered 2T. But having read in the Servicemen's Reference Book that the operating pressure for the D4400 should be 30 pounds, I'm now thinking maybe this gauge won't be suitable? Anybody used this gauge on a D4400? And if it's the wrong gauge what should I be looking for instead?

Regards,

Ok, thanks for the info guys.

So reading that bulletin from Eddie it says in there about operating pressure being 30psi for those engines too so that makes me think the 7F-9084 will work for the D4400 too. And Handy on startup as it’s more sensitive or am i missing something as usual?
