What am I looking at? Gulfstream 232

[jmenende]

Howdy folks. Just upgraded to a 1999 gulsftream 232 with dual ox66 150hp. I think these are fuel pumps but im not sure. The lines come from the valves, through them and out to the engine.

Also, I have included another foto of a valve that connects to the toilet outlet. What does it do?

Thanks in advance.

I think those are lift pumps but I am not sure why you would have them with OX66 motors that have their own low pressure pumps.

The second pic is the overboard discharge/pump out selector valve. Normally it should be in the pump out position and either disabled with a lock, a tie wrap, or by removing the handle. It would only be unlocked when discharging waster tank contents in legal water areas.

Technically even if the selector is in the dockside discharge position but not locked/secured, you can be fined.

The OX's lift pumps have a finite lifespan because of being made out of a thin rubber diagphram. Generally, an electric lift pump is more reliable.

That said, I've neve personally seen an electric fuel pump that looks like that - not to say that I've seen everything, though. But I'm curious aobu the "T" being used.
