My grandfather gave me a tille with a 5 horse briggs engine. The gas
tank is metal and rusting. I cant find a replacement. I have cleaned
it out numberous times but eventually the rust peels off again and
gets caught in the filter and it wont run.

Is there a way to fix this? Make a new tank or is this a lost cause?
This tank is the type that the carborator mounts directly on top of
the tank.

Sounds like a B&S Pulsajet system. The tank is more than just a gas
holder, it's got an elevated cup that the venturi sucks gas up from.
No float. You could probably carefully clean the rust out, then coat
it, making a new tank would need you to build that cup into it.
Google "Pulsajet" for more info on how to identify, clean and adjust.
They normally work pretty well until the rubber diaphragm craps out.
I've seen other posts on 5 H.P. Briggs engines with rusting out
Pulsajet tanks, so you aren't the first. Your only other alternative
is to find a dealer that has a good scrapper pile and find a donor
engine.
