***BACKORDERED - Alternative Available*** Unfortunately, our OPT-HD5GP are back ordered until mid to late September. We do however have an identical pump for the same price, that attaches with a PVC adapter and hose clamp, instead of the metal clamp that attaches to the lid. Please contact us for pictures. ___________________________________________________________ Don't want to cary a 5 gallon pail to the fueling station with you? Use this heavy duty metal pump to dispense product into smaller, easy to carry bottles. Dispenses approx. 4oz (150cc) per stroke. Avoid the mess of funnels and spills. This pump slides into the top of the lid fixed in place with a washer and metal bracket, allowing for easy use and storage.
