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.
I have a manual guage hooked in line between the filter housing and computer cooler is that a good spot?
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.
can i test it anywhere in the pressure line
Yes. That will be fine.
You should have at least 65 to 90 psi pressure.
