Does the gen and engine use the same Racor?

I don’t know. I have been looking for a fuel system schematic but haven’t found one yet. This is on an sp.

I had a pick-up that ran me crazy for a while . It was a little more random , but similar symptoms . Turned out that my fuel pickup tube had no screen on it and there was a piece of trash floating around in the tank that would occasionally plug up the fuel line . It would clear up after sitting for a while and run fine until the next time .
Faulty electric fuel pump or collapsing fuel line sound plausible too.

Doesn't sound like the tank is getting a vacuum on it .

Andy asked a good question , does the generator use the same filter as the engine ?

Does the generator get it's fuel from the same fuel line coming out of the tank ?

I found some reference to an addon pushbutton switch and facet electric pump that was also connected to an oil pressure switch. I would mess around with that, hotwire the pump to make 100% sure it's on, then see what your vacuum does. It might be the case that just cracking the filter loose just relieves the pressure until you drive it a bit.

Also, is there a check valve in that system somewhere that could have been installed backwards when the engine was getting worked on?

Found a post of Jim Brookshire's from 2013 . He stated that on his Sp , the generator and engine shared the same fuel line .

Thank you, thats good information. I am about to change my electric fuel pump and see if that helps.it is before the racor, so it is making me wonder if it is the problem. The fuel filters I changed look as nice as when I put them in. I imagine for that vacuum level I should see some fouling if the filters are at fault.

IF problem was bad fuel clogging RACOR filter you would see the gunk on the outside of the filter. Very easy to see. Symptoms sound like fuel delivery for sure...fuel pump, fuel line?

You’re in a safe spot...that’s good.

Many fingers are crossed for you!

Pump should be key on, oil pressure switch is for gassers. I realize there are many wired w/oil switch, not my choice and not necessary, do as you will.

[Harold,Cat&Sam]

I was wondering , does the electric fuel pump also feed the generator ?

Does the generator have it's own pump and filter ?

The answers to these questions , me not know . Maybe someone with SP experience will come along with these answers .

In addition the 8.0K onan has a fuel pump, it has a strainer screen on the bottom, that can be cleaned. these facet fuel pumps can tick,tick & not deliver fuel. there should be a rubber hose to the 3208 fuel filter housing on the bottom of the 3208, check this hose.
