Parts Desk Insights
Best Use Case: A strong choice for replacing or upgrading a below-deck permanent fuel tank where a compact, integrated fill/withdraw/vent layout is desired and 3/8" withdraw connections with swivel routing convenience help during installation.
Common Issues: Plan installation around the tank’s integrated fittings: confirm hose routing clearances and that your withdraw/vent hose lengths and routing allow for proper connection without kinking. When sizing the cutout/space, remember tank dimensions exclude fill and fittings.
