I have an extra trash pump and 325gal tank, an associate said I should put together a hydroseed unit. Never even thought of it so have a few questions. 1. The pump is a pacer with a 5.5hp briggs. Is this enough for a small unit? 2. It has 2" ports. What hose is a good match for this, 1.25"? 3. What spray gun should I look for? Thanks.
