Does the size of a fuel filter matter?

[FiatJim]

I've seen several different sizes used. Does it matter? Also, what's better to use: metal, glass or plastic (can see through)?

ive been using the fram g-2 for over a year and it works fine-- carb eng

the size will determine how often it needs to be changed. The see through are kind of nice for monitoring the amount of dirt in the system

I know a lot of people put one between the fuel tank and pump to protect the pump. One of our members had to replace his pump. Then another before the carb.

I hadn't thought about putting one before the fuel pump. Was his an electric pump?

I'd read some opinions about the plastic ones being melted by engine heat. Hasn't happened to me - but then again, it only has to happen once to really ruin a good day I like the idea of being able to see the actual filter material.

I purchased the plastic clear ones from IAP and the solid aluminum ones from Auto Ricambi. I never thought about the engine heat. I was going to install the clear one in the engine bay. Maybe I'll switch them up and put the clear plastic one in the trunk. I wouldn't want it to melt.
He did have an electric pump.

my wife says size doesn't matter - of course, she might be just trying to be kind...

I've never seen a plastic one melt, but then again I wouldn't lay it on the exhaust manifold either

I have installed a translucent plastic, small pre-filter between tank and electric pump on my FI car, and the standard metal filter in the pressurized FI fuel line after the pump. The pre-filter is a just-in-case filter, to monitor and change as often as required. Non-pressurized lines - easy, quick. Not near engine or exhaust.

Where do you think the see through one would benefit most? Before the carb or after the tank?

[DUCeditor]

I use the see through plastic filters front and rear. Frankly installing it in the engine bay made me a bit nervous but that was all in my head. Leaks do happen -- most often in the connection points. And if the plastic had been black I wouldn't have hesitated a blink.

On my carbed `77 the filter is no where near the motor itself and on the opposite side from the exhaust.
