1976 SRV190 fuel pump

[WISCONSIN_SRV190]

Hello,
I am looking for a recommendation for electric fuel pump for my 1976 SRV190. It has the Mer233 ( Ford 302 ). Fuel tank is mounted in the front of the boat, above the floor with a top mounted fuel line. Fuel line is around 15-16 foot long.

I was looking into a Walbro FRB-13 because it states a lift of 48" but I am new to boating and really don't have a clue what I need? I will also be purchasing a painless wiring harness for installation.

I know some might ask why I am going away from the Mechanical pump? Well I am having fueling issues. If boat sits a day or two it wont fire up without a shot of ether. sometimes when I hammer it down it falls flat on its face, I have to back off throttle and then get back into it. Also sometimes it wont fire back up after running and shutting it off for a bit without a shot of ether but if I shut it off and start it back up it fires right up. I have flushed fuel tank, replaced fuel filter, fuel lines, carb with a Holly, mechanical fuel pump, coil, insulated fuel lines, ran boat with blower motor on, ran boat without cover on motor. none of this has mad a difference. I ran a test gas can and primer bulb back by the motor and my issues disappeared.

Any help pointing me in the direction of a good pump for this application would be very helpful.

Thank you,

Jared

Is the vent on the boat mounted fuel tank working properly.
What is your fuel pressure reading when the problem occurs?

I checked the vent when I flushed the tank and it appeared to be free of obstructions. I will pull the vent line and double check the screen going through the hull.
My boat doesn't have a fuel pressure gauge. I do have one laying around my garage I could put inline and do a test but that would have to wait another month, I live in Northern Wisconsin and the lakes are still froze over.

With the age of the engine, have you checked cylinder compression? Worn out rings, bad valve seals or misadjusted valve rockers could cause poor vacuum in the intake and it doesn't efficiently draw the fuel air mixture and compress it like it should. Also with the age I assume the distributor has a points and condenser set up. When was the last time you inspected, changed, and/or adjusted them? For a carbureted engine its either getting fuel or not. The fuel pump only has to make about 4psi to work and I have never seen one break in such a way that it only works intermittently. The way you describe your situation I would have first leaned towards a carb needing a rebuild and possibly a defective choke mechanism. But you said you changed it out. Are you sure that the new one you mounted is jetted properly for your engine setup? A lot of what you described sounds like a lean running motor issue.

The engine was rebuilt at time of restoration and has electronic ignition. I never thought of running a compression check as it didn't see alot of run time after it was complete but I will definitely do that when I pull her out of storage. As for the carb I thought i had it tuned well but I could be wrong? I did my best with that and would need to take it to someone that knows more about them then me.

What stumps me about the whole thing is when the boats running it runs perfect and when I tested it with the Jerry can back by the motor I didn't have any of these issues.

I appreciate the help and will I take all the help / info you have.

Thank you
