I have an OPEL ASTRA H (A04) | 2004.01-2014.05 - 1.6 (L48) - 1598ccm 105pk petrol car, which has the fuel filter built into the fuel pump, which is located in the tank.
The pump and fuel filter are not separated, and if you want to change the fuel filter, you have to change the pump. This is very expensive and complicated to do.
In order to protect the car from damage (which will eventually happen), I want to add an fuel filter to the fuel lines. I can then change the filter easily when needed.
I read Can I add a fuel filter to an Astra H 2005 Z16XEP, which states it is possible but I need to know the pressure for the supply line.
Is this safe to do, what fuel filter do I use, can the pressure in the lines change. Will the fuel pump have to pump harder and maybe get over worked with the added fuel filter ? Do I have to install it after or before the fuel pump or can I add two filters ?
