Has anyone rigged larger tanks to trash pumps for longer run time

looking @ gas Honda, about 500GPM- if anyone has diagram on how to do it- maybe some type of hose rig? Thanks- this pump has auto shut off low oil so should be fine to double or triple run time

At 500 gpm, is that a 4" pump? I run a 3" on a 12 gallon tank and it will run the pump about 30 hours. I built a table with steel legs that I can stick down in the mud. Makes the table secure and it is easy to level the table. I put an inline filter in the line and a shutoff valve. The shutoff is important as you may need to tear down the setup with gas in the tank. It also makes it easy to bleed the air out of the line.

Not the diagram you are looking for but saw this and going to do this for trash pump and also ice eater in the event of ice next year. Look forward to help on the info on fuel lines. Thanks

Not sure what you have going on with your table but I think you have the generator and the fuel tank at the same level. The tank needs to be higher so it will gravity feed. I would set the bottom of the tank level with the top of the generator. Do you have a outlet on the bottom of your fuel tank?

Love to see diagram. Think if you gravity feed and get her started a tank above the OEM tank (like 1.8 gallons I think) with proper feeding should work w gravity alone. No shut off needed. Thoughts? Like run tanks in parallel.

Not my design but pulled the picture off of Google as an example of what someone did. Would be nice to get more pictures or examples of what has worked for others. Thanks

We rigged one up with an air hose with foster fittings. You just need to make sure that The gas cap on the tank on the pump is not vented, otherwise the gas runs out the vent. Of course your upper tank that is gravity feeding the pump tank would need to be vented. Probably other ways to do it, like bypassing the tank on the pump but we just rigged this up quick one day.

In the upper picture the line is not yet connected to the fitting on the bottom of the tank.

Yes it will gravity feed. You just need top make sure the gas cap on the pump gas tank is NOT vented. Otherwise all the gravity fed gas will just run out the vent. Once you solve that problem, just make sure the higher tank that is gravity feeding the pump tank is vented. Works like a charm

That setup looks too complicated to me. Just get a gravity feed tank, elevate it above the carburetor, disconnect the fuel line on your existing tank, hook up your new tank and fire it up. The only issue I have had is bleeding the air out of the longer fuel line. a shutoff near the end of the line (close to the carb) will let you bleed the line just before or as you hook it up. My only concern when I do this is not having a leak or losing any significant fuel at the duck lake. I put disconnects in my lines so if anything leaks I can turn it off and get it away from the lake. Edit: The biggest problem I see with the setup pictured is if the seal on the fuel cap leaks you loose a bunch of fuel.
