What a PO of my 1975 Newport 28 did to the electrical system (which I've finally worked out), he also did to the fuel system. Rather than the basic "tank to a filter to the pump to the carburetor", he had the line from the tank going to a pump, then to a glass, non-Coast-guard-approved inline filter, to the original fuel pump, then to the carburetor. He had also disconnected the original fuel pump's power supply from the oil pressure switch and made it a permanent manual switch on the dashboard. To start the engine one pulled the choke, turned on both pumps, then started the engine, remembering (hopefully) to turn them off when the engine stopped.
Since my engine has recently decided to basically not run any more (starts OK but won't go above an idle and that only with the choke full out), I figured I'd reconfigure the fuel system back to the original design and start from there. I don't have a Racor filter yet, so I replaced the glass filter with a regular steel-body filter, and put a primer bulb in place of the first pump, since I'll need that later for the Racor anyway.
So now my system is tank to primer bulb to inline filter to pump to carburetor. I checked the flow through each piece of line to make sure that there were no blockages, and everything was fine. Finally, I pulled the line from the pump off the carburetor and put it into a jar, then started the fuel pump to see how the original equipment was working.
Thus my question: when I turned the pump on, the fuel came out (and looked and smelled OK to me) in a nice pulsed stream that would have filled a pint in about 30 seconds or less, I'd guess (I only let it run long enough to verify it was working).
Does that seem like the correct flow rate for that pump? The fuel didn't come out like from a garden hose, but at a good clip that certainly seemed like enough to run the engine.
Unfortunately, when I tested the arrangement the engine started up nice and I was encouraged, but then I saw I'd forgotten to turn the pump on and the fuel burned out of the carburetor before I could get to the switch. Afterwards I couldn't get it to run as well, but I didn't have any more time to reprime the line so I left it for next time.
I apologize for the long story, but basically all I need to know is "Does that flow rate sound about right for that pump?"
Thanks!
