(2) Gas Filters, Should I remove one of them?

[Ark Bigfoot]

72 Bronco. I had a leak in the 13 gal tank and the 4x4 shop replaced it with a used one. It was rusty and I put in an in-line gas filter because it would plug up my filter at the carb. I am now replacing the old tank with a new one. Is it okay to leave the in-line filter in or should I remove it. I don't know if it puts more pressure on the fuel pump. Or perhaps leave it it.

Hi, I run two filters, one before the fuel pump and one before the carb. I've done this on my carburetor engines for many years. Good luck

 

[Ark Bigfoot]

Thanks. I will leave it in.

Two inline filters is considered by some to be overkill, especially when you're installing a new fuel cell; HOWEVER, I merely think of two filters being cheap insurance in the event you get some crappy fuel, i.e. the bottom dregs at the gas station. Never hurts to have cheap insurance, IMHO.

it may be an issue if you use 2 filters after the pump. I hate the stock Ford filter at the carb and only use 1 good filter just before the pump. If you use the stock filter make sure the tube and hose go straight in so no offsetting of the hose. that way no stress on the fuel line and less likely to leak. I hate under hood fuel fires and have dealt with them several times. use marine A1 fuel lines where ever possible not auto parts crap.

if you want to avoid the bottom dregs don't buy gas while the Gas truck is delivering gas. it dumps so much fuel the empty tank at the station gets all stirred up.

In a way there are 2 filters in a stock fuel system. There is a sock/screen inside the fuel tank. This should keep the big chunks from making it to the pump. Experience has shown me that these tend to fall apart or fall off over time.

The second filter is the one we think about, the one just before the carburetor. This one is a fine filter to keep the small stuff that can pass through the pump fine but won't pass through the carburetor.

Most of the aftermarket tanks don't have a pickup screen.

If there is a filter before the pump it should be a course filter. Something that stops the big chunks but not worry about the fine stuff. This will keep the pump from starving for fuel. At least minimize it.

And just because a tank is new don't assume it's clean. If it's a plastic tank, or a reproduction of the factory tanks, they don't tend to need as much pre-cleaning as do the aftermarket fabricated steel tanks. But it would never hurt to swish something around inside to make sure.

Yeah, that's true BUT I have rolled into the only gasso within fuel range (exceedingly poor judgement on my part) and didn't have any option but walking. Lol

All cars and trucks from the 30s at least till the throttle body injection was introduced had fuel tank filters and one between the pump and carb. There's nothing wrong with this arrangement and the Ford filter on the carb. I've run the OE Ford carb filter for over 100,000 mi. and a new one is easy to carry in the glove box or tool bag. The tanks do require occasional cleaning and we know that's a real PITA. That's not an excuse to not do it. I've found that fuel filters between the tank and the pump invite vapor lock. So it's no coincidence that vehicle manufacturers didn't do it. Rusty's point is a good one. Avoid gas stations getting a fuel delivery unless you want to drop your tank for a cleaning.
