Fuel Filter Change

I haven't heard that saying, so I guess I've been successfully doing it wrong for 30 years. Heard way too many stories of engine fires from filters up by the carb.

Well I don't know about wrong or right placement of a plastic filter element but I do agree that mounting the filter down low prevents covering everything in gas if it fails.

It's my understanding that paper filters are slightly more of a restriction than SS due to their density, and this can cause extra strain on a pump. Block mounted pumps rely on atmospheric pressure to get fuel from the tank with minor suction occurring, and fewer restrictions is always better. If the paper filter should disintegrate then the pump can become clogged, the other option of course being the inlet screen on the carb. It's also worth noting that paper filters in a plastic housing shouldn't be mounted pre-pump, as the thin walled ones can flex in and out and lessen the flow. But for most people it's probably not an issue.

I like to put the filter between the frame hardline and the fuel pump. Keeps any risk of leaks down low off the engine. I had a friend that had the glass one leak up on top of the engine, so ever since then, I've always thought about the what if's.....

Same way I run mine, have for years, never an issue

Im sure the way i've put my fuel filter above the front of the intake for now looks unfavorable to some, but i plan on fixing that.

When i get the chance, i plan on installing the filter just after the ouput of the mechanical fuel pump so it runs vertically along the front of the engine block and cylinder head so its better cooled by the belt driven fan when on the road.

That's exactly where I've mounted the Clear View and others and it worked great.

I honestly can't believe that anyone even uses those glass filters anymore. Not to mention that they shouldn't even make them or be legal to use. The only thing they are good for is setting your car on fire. They just screw together and have no way of locking tightly and since its glass you can't torque them very much. So what happens is they constantly come loose from the normal vibrations of driving and the engine running.
I have seen way to many nice cars burn to the ground from a fire caused by a fuel leak and guess what filter a good majority of them had....

I have used the glass filter for years, never leaked. OEM used glass bowl filters for years decades ago.

I've never had an issue with the glass filter but I've only used them for about 40 years. My 383 uses -6AN fittings so it had to be changed. Mine is also mounted vertically right after the mechanical fuel pump.

Most times I see them, they're in the middle of a length of hose that isn't very well-restrained.

The OEs used glass bowls at the carb for a LONG time (out of harm's way) Hell, my tractor still has one on it.

I feel like the glass would be best higher up, near the carb, to prevent the possibility of road debris striking it, although that's a pretty small likliehood in the grand scheme.

I just use the metal filter and change it every couple of years, but I started with a new tank and sender
