If you believe this, I've got some swampland I'll sell you at half-price. I've removed MANY restricted fuel filters from cars today.
The MORE restricted the fuel filter is, the harder the pump must work.
I've only had one fuel filter line that leaked after replacing. Guess WHY?
No one had replaced the fuel filter in years, just like this guy is recommending not to replace them. LOL!
