| Is there a timeframe when to change your fuel filter? Or do you guys just go by how it looks |

I presume you mean the plastic aftermarket filter we always tell folks to get out of the engine bay?

Too many variables for a one size fits all answer. Is the car driven every day? Is it stored inside? Exposed to salt or chemicals? How often are you on dirt or gravel roads? Are you using ethanol rated hoses? If money ain’t a problem then change them all the time. I don’t and I can get 3 or more years on a filter but if you take into consideration the above and can do a proper visual inspection you’ll be ahead of the curve. Another school of thought says if the tank is clean and the sock OEM filter in place then add on plastic filters are unnecessary. Of course I did a new tank with sock and add on filter because it’s like belt and suspenders. If that ain’t enough run the OEM fuel pump it has a filter too. |

I don't run a fuel filter on my 1970, and that also get used to drag a harrow around a horse arena.
My 1971 has an 1835cc engine with a single Weber 40DCNF and I read something like 40 years ago that the Weber idle jets were small, so I use an all-metal gas filter between its mechanical fuel pump and the Weber.

The Factory Fuel filter in the owner's manual in my 64 Beetle says to clean he screen every 3,000 miles. See the link below.
https://www.thesamba.com/vw/archives/manuals/64bugowners/page_84.jpg
Note; that about 1971 VW stopped putting the filter in the fuel pump discharge to the carburetor and that's when VW parts departments were authorized to start selling plastic fuel filters. I was a Dealer line mechanic at that time, a little later I was in Unit Repair. We saw a lot of fires in those days and the biggest problem was the pressed in fuel tube to the carburetor always popping out, same true for the pressed in fuel tube to the discharge side of the fuel pump. We used to slightly bend the tube and knurl it, then epoxy it and press it back onto the carburetor and fuel pump. The other fire hazard was the fuel line that goes through tin and out over the transaxle. There is a rubber gromet the fuel line goes through the tin and the gromet which is made out of rubber gets hard and cracks and falls apart leaving the fuel line to rub against the tin right over #3 exhaust port to get sawed in half. Never saw a melt down of a plastic filter. Saw some fuel hose leaks though. |
