Indmar TBI fuel pressure question
 

Hi,

When I turn my engine off, the fuel pressure drops down to 0 psi over the course of a few seconds. I'm wondering if this is normal or if it should hold pressure indefinitely or at least much longer. I put in a TBI rebuild kit to fix a slow drip from the injector O-ring, and that included a new fuel pressure regulator diaphragm. However, the fuel pressure behaved the same before and after.

Thanks,
Mike

It is normal for the fuel pressure to drop to zero after engine shut down on a TBI engine.

Good to know. Thanks!
