In regards to the glass fuel filters, are they able to take the pressure of the fuel injection systems? I just replaced my fuel filter can, and the gas that came out was darker than mud. I put on a new filter, but would like to put on a glass one also, so I can check it often.

thx

The fittings are probably more the limiting factor than what the body of the filter is made of. All of the glass ones that I've seen are the type with hose barb ends, which typically means low pressure application, all of my vehicals with EFI use the metal canister type with inverted flare fittings for the higher pressure. If your Z uses the type with screw in fittings, much like a brake line, then no you probably can't use a glass type unless it has matching fittings. The old fashion type that fits inline using hose and clamps would probably leak or blow off if it clogged, not enough friction between the clamp,hose, and metal fuel line.
