Correct, all pumps have a mesh filter. But the Thor does not have a replaceable fuel filter as do other models.

OK. Thanx... But how can affect in my entire fuel system if i put a fuel filter like GEMS??? And another questions the fuel pump pressure in ThOR is the same as the GESM ??? (Fuel pump pressure on GEMS is 3.5 Bar).

The fuel pressure for the GEMS is (up to 99MY) 2.4-2.6 bar or 34-37 lbf/in²
The fuel pressure (Thor from 99MY) is 3.5 bar or 50.75 Ibf/in²
up to 99 it was sagem - lucas after 99 it is Bosch Motronic
Injectors
up to 99MY Lucas D1000
after 99MY Bosch EV6C
There is no similarity in the two different types of fuel pump. The Lucas system has an inline fuel filter (on the chassis) and the fuel pump has two connectors one for delivery and the other is a return pipe. On the later Thor there is only one outlet as there is no return to the tank. Although there is a cause filter on the bottom of the pump there is a finer one inside the pump. It would not seem adviseable to mess with the system. I have had several p38s and never had any issues with filters on these cars. If anything the Thor is the better system.
