This is a question that I *THINK* that I already know the answer to, but I want reassurance.
This Swisher Trailmower I just got has a 14HP Vanguard on it. Bolted down, pulleys and belts all connected, but it has no gas tank. I have a tank I want to use but the only place I can really mount it the bottom of the tank will be even with or lower than the engine sump let alone the carb and fuel inlet.
Most engines that I see with fuel pumps even, still typically mount a tank so that the bottom of the tank is above the carb inlet (kinda defeats the purpose of a fuel pump because with that sort of mount all you really need is gravity)
I "could" mount the tank higher as in over top of the engine I guess/ but it would look stupid with the rest of this combination, and it would also tend to get in the way if you wanted to mow around something with low clearance.
this vanguard has the vacuum pulse style fuel pump on it rather than the mechanical style like I'm so used to seeing on cast iron Kohlers and even some of the old Tecumsehs.
The tank I have is an oval style steel one like what used to com on the (way) older Kohlers, it's like 6 qt capacity might even be a 2 gallon.
My plan was to make a mount bracket next to the engine mount base between the belt drive and the wheel. It would be like a 16-18" run from the bottom of the tank to the fuel pump inlet about 1/2 uphill.
The fuel pump on this Vanguard should be able to handle that if it is in good working condition, right?
My plan is to use 1/4" steel tube probably like the stuff used for automotive brake and gas lines with just the last 2-3" on each end being rubber fuel line. I did the one on my Woods Zero Turn that way but that one runs pretty horizontal from tank to carb. The other difference is that Woods mower has a cast iron 12 HP Kohler Magnum with a mechanical pump driven from the cam.
