No kidding, our Bobcat mini excavator uses a grease gun to tension the tracks on it.....it is effortless.

When running fuel into the cab, I wouldn't use anything other than stainless braided hose or hydrualic hose with the appropriate fittings.....it just isn't worth skimping on this plumbing in the least, IMO.

Here is how my set up works......hardline off the filter housing to the needle valve and teflon lined braided hose from the needle valve to the gauge.
