What is the safest and best fuel filter to use on a big block. Had a steel one (cheap one) leak a few years ago but fortunately did not start a fire. Don't want or need to worry again.
WIX - they are the only fuel filters I trust. You can also find them under NAPA's house brand. You'll want a 100-micron fuel filter before the fuel pump, and a 10-micron fuel filter after the pump. If you're experiencing 'vapor lock' or fuel percolation issues, it's a good time to install a WIX filter with a fuel vapor return line [Part # Wix 33041]. You can run this to your fuel filler neck, it doesn't need to be plumbed into the OEM tank.
I use 2. One between the tank and pump and one between the pump and carb. Metal and away from heat or shield it.
But what type of pump?? Positive displacement piston pump or rotary vane type, which is the general type used in submersible in-tank pumps. I'm curious as to the reason suggested.....other than to sell more stuff....Holley recommends a filter before it's electric pump.

View attachment 1084403here's a nifty little strainer I use In my carbs.
It goes right behind the hard Line fuel fitting at the carburetor.
I just installed my two carb strainers this past weekend. My question is are they suppose to float inside the chamber or are they supposed to fit into the brass fitting? My old ones fit into the backside of my brass fittings, the new ones didn't fit into the fitting. How did yours fit?
Uh, electric pump, or mechanical? Stock, up by the engine, or back by a rear mount electric pump.What is the safest and best fuel filter to use on a big block. Had a steel one (cheap one) leak a few years ago but fortunately did not start a fire. Don't want or need to worry again.

The only problem with putting a filter on the suction side of the pump is: it ADDS to the suction pressure loss of the pump and system. Adding to the suction pressure loss reduces the overall pump capacity, both in terms of VOLUME and PRESSURE capabilities. IF using 2 filters were such a good idea, why didn't the manufacturers do do? BTW....filters are rated on their micron rating (particle size to be trapped). Defination of a micron: "micron" is an abbreviated term for "micrometer", or a millionth of a meter (1/1,000,000 meters). This is about . 00004 inches. For Size comparison, a human red blood cell is about 5 microns across. This small size will pass thru the carb or EFI without consequence. Just my opinion of course.
