hopper tanks?

[460_f100_dude]

what exactly is a hopper and what does it do???

 

[topfuel443]

a hopper tank is a small remote (or some hoppers are built in) tank that is placed in series with the main tank. the main idea is that the fuel will remain at a constant level (full) in the small tank even though the main tank is getting emptied. in doing so, it allows the needle setting to remain more consistant throughout the entire tank full. Not sure if you are aware of this but, as the fuel level drops the engine will start to run leaner and leaner as the level gets lower and lower. This not good.

It also helps with "foaming" of the fuel. when fuel foams from vibration and normal abuse of racing, it can create air in the fuel line going to your carb causing lean conditions and/or shuting off. This is not good.

The more full you can keep the feed tank the more consistant your boat will be.

hope this helps~ James

what sort of baot ae you running for the picco 91??

i have a hopper tank slightly higher on my mono as it helps with the constant feed to the carbi on the cmb 90.

on my hydro 45 i have it side by side. but will soon have a grim tank built for the hull.

more info is needed to give you the best help in setups and the way they are to wok for you in the best way.
