Not really. The standard USCG hose is fire rated. The fuel bulb is not.

USCG requires fire rated fuel hose for inboard gasoline installs and a fuel bulb is not rated and cannot be used. No such USCG requirement exists for recreational diesel engine installs. There is very little in the USCG regs when it comes to recreational diesel inboard installations.

That said. A properly installed squeeze bulb makes for a good fuel system design and I use them.

If you want to meet ABYC regs, that's a different story.

It probably doesn’t matter much but the Racor filters are designed to be on the suction side of the fuel pump.

If you install the primer before the filter, loosen the filter top when you prime it to let the air out as it fills.
