5000 gasser - gravity feed?

Long story short - I have to replace at least some of
the fuel line, and there's a possibility the pump may
not be good. Options are 1) replace as original, 2)
use a low psi electric pump, or 3) gravity feed it.
Would gravity feed work? The inlet on the carb IS
below the fuel tank, but I'm wondering if it will starve
when being worked hard or when the fuel level is
low.
 
My 192 ran fine on gravity feed through an inline filter.
I've never had a chance to really put the pork to it but it ran fine WOT up and down a few hills so that the governor was kicking in.
192 isn't as thirsty as your 233 or 256 what ever it is.
I happen to have all the oem lines, sediment bowl and fuel pump here so some day I will put it back to original.
If I didn't have that stuff in my back pocket I would do as you are thinking and run a small electric pump on it. Make a nice clean job of it.
Probably save the next owner some headache if he ever has fuel problems.
Major pia to sort through all the filters, etc as it came from the factory.
 
Yours runs on gravity?
Mine isn't so technologically advanced as it still runs on gas but is gravity flow.
I'm hoping to get that upgrade installed before the fuel prices go up again.
His 5000 ought to do pretty good as it's heavier than ours.

Shoot they all run good on gravity as long as you park them on top of a big enough hill but the problem is when you run out of hill you run out of gravity to run them
 
I imagine it would work but you may need to keep gas tank filled above a certain level to have it work well at all uphill/downhill situations. Maybe you could temproarily bypass pump and try it ? If your pump is bad now- you are already doing it. On my 4000 screen in pump fitting can get plugged and would mimic bad pump .
 
Project tractor that isn't running yet.
Am probably going to try it gravity feed, at least to see how it goes. I have an electric pump, so that will likely be the route I go. I'm sure there was a reason Ford put a pump in there...
 
Holley carbs generally don't like gravity feed especially in high load situations. There is always a group that gets along differently from the majority. Your mileage may vary.
 
At work we had a chipper with ford industrial engine, mechanical pump died on the job onw day, I tossed a 4psi adjustable pump on to get us back to work. Not original, but worked.
 
That's actually where the pump I have came from - a Red Tiger industrial. Sold the engine, but kept a couple goodies from it.
