Hi. Thanks for using JA! I can help you with this.

 

Could you get me the engine serial number please?

 

There are several types of filter housings and they each have different locations for checking fuel pressure.

 

Thanks!

Thanks for the information.

Let me do a little digging and I will be back in a few minutes.

Customer replied894 days and 5 hours ago.

I have a manual guage hooked in line between the filter housing and computer cooler is that a good spot?

Expert:  Cat Man replied894 days and 4 hours ago.

Here are 2 possible locations. I say 2 because with your serial number, you could possibly have either one.

 

Please let me know if you need anything else.

Yes. That will be fine.

 

You should have at least 65 to 90 psi pressure.
