Apparently they are Composite, not Aluminum. And pricey

A MARINE fuel system. That plastic fuel filter is a time bomb waiting to go off.
While the eng itself is basically a car eng, almost everything else attached to it is specially designed for a boat.
This includes fuel delivery system, carb, alternator, starter, exhaust and cooling system.
Fuel delivery sys should include a metal filter/water separator and fuel hoses rated for use in the eng compartment of a boat. Mechanical fuel pump, if equipped, should have a separate hose connecting fuel pump to carb in case the diaphragm ruptures.
Carb should be marine style and have a J-tube for float bowl vent (and the throttle shaft bushings are tighter on marine version).
Alternator and starter for marine applications are specially designed to not arc and cause an explosion if fuel vapors are present.
If that's an automotive water pump, it won't last very long in a boat pumping pure water.
Remove the air filter and take a pic of the carb..
You can post pics after 10 posts. Just make a series of posts saying post 6, post 7, etc.

The plastic fuel filter is the only issue, not the rubber fuel lines, as long as they are rated for fuel.

Here's a bunch of different Q-jet models that all have them.

Here's what I call a J-tube:

There are different ratings depending on where in the boat they are installed.
Type A1 is the type you're supposed to be using in the eng compartment. There's a lot of professional boat mechanics that don't know this and a lot more shade tree mechs that don't.
Fuel line and fittings
I know there are tons of boats out there running around with automotive fuel lines and they haven't burst into flame yet, but if you want it done by the book, you'll need some A1 rated fuel hose in the bilge.
BTW, If the insurance company investigator knows his $hit, he'll be looking for that when he arrives to examine your burnt boat claim. The liability isn't something I personally want to risk but to each his own.

All the marine ones I've seen had a single J-tube.
