Default Fuel pump replacement '96 Voyager 3.3

I searched the forum but was unable to find anything about fuel pump replacements, but I'm sure that I missed something because fuel pumps are broken very often I'm told.

Now, what I was wondering is; do I need special tools to replace the fuel pump motor/filter. Is this something I can do myself?

I already have one so the work can start as soon as I'm sure what to do, and this is the first one after over 330.000KM so we can't really complain.

Many thanks in advance for your help and tips!

I don't think you will be able to do it without this tool its shaped like a U with a grove on both legs, this releases the pump module.

Probably better to take to a dealer

The fuel is pump installed and the car starts again, but I can't floor the pedal without stalling the engine. Like it isn't getting enough fuel. What should the pressure be on the injection rail?

We checked the pressure earlier today, and there's only 15psi on the fuel rail. That must be why it has troubles running on petrol it runs fine on LPG.

Wiring to the pump is fine. Must be some other stupid error on my side.
