Motobilt Fuel Cell Mount for 30 x 12 x 12
The Motobilt kit is a CNC laser-cut, 16-gauge steel mount with a press-brake formed design. It includes an under-tank plate cut from .125 inch high-strength steel and ships bare metal for painting or powder coating. Bolts are not included, and the fuel cell is sold separately. Best for builders seeking a rigid, heavy-duty mount that can be powder-coated to match a custom color or finish. Limitations include the need for paint or coating and verifying compatibility with your specific fuel cell model, as the top of the cell must be checked before ordering.
Who it’s best for: Off-road and custom builds needing a robust, bare-metal kit that accepts after-market finishes. It’s especially suitable for applications where the user wants a fully customized look after installation.
Why chosen: Strong steel construction and a compatible under-tank plate provide reliable mounting for larger cells, with the option to tailor finish and fit.
Part Synergy Fuel Cell/Tank Brackets Kit
The Part Synergy kit is designed for direct OE replacement and easy fitment. It matches factory specifications and has undergone quality testing to ensure reliable performance. This kit emphasizes direct-fit compatibility, minimizing installation time with no required modifications. Caution: verify that your fuel cell model aligns with the kit’s mounting points to avoid fitment issues.
Who it’s best for: Builders seeking a straightforward, plug-and-play solution that preserves factory aesthetics and fitment. It’s ideal for restorations or street builds where exact factory-like mounting is desired.
Why chosen: Reliable fitment with tested compatibility makes it a strong choice for users prioritizing simplicity and original-look installations.
RCI Fuel Cell Mount, 20 in Wide
This mounting kit is built to fit an RCI 15-gallon aluminum cell with a 20-inch wide opening. It’s designed for a broad mounting space and is part of a modular system that supports various configurations. Best for larger cells that require more mounting area. Limitation: ensure your fuel cell’s top surface aligns with the kit’s mounting points for a secure fit.
Who it’s best for: Users with wide, 15-gallon aluminum cells needing a dedicated, expansive mount. It’s well-suited for high-capacity builds demanding extra stability.
Why chosen: Large width compatibility provides stable support for bigger cells and reduces risk of side-to-side movement at speed.
RCI Fuel Cell Mount, 12 in Wide
The 12-inch-wide RCI mount is designed for use with any RCI fuel cell size, featuring heavy-gauge steel construction and pre-bent shapes for an exact fit. Mounting hardware is included, simplifying installation. Best for tight spaces where width is a limiting factor. Limitation: compatibility depends on the chosen fuel cell’s dimensions and mounting hole pattern.
Who it’s best for: Builders working within constrained under-car compartments or narrow engine bays who still need solid cell support. It’s a practical choice for off-road builds with limited space.
Why chosen: The pre-bent, heavy-gauge steel design reduces precision errors and speeds up installation while delivering sturdy support.
RCi 7515A Aluminum Fuel Cell Mounting Kit
The RCi 7515A kit is positioned for 15-gallon aluminum cells. It emphasizes aluminum construction and a straightforward mounting system. Best for users seeking a lighter mounting option without compromising strength. Limitation: specific compatibility information beyond the stated capacity is not provided here, so verify cell dimensions before ordering.
Who it’s best for: Builders prioritizing weight savings and corrosion resistance while maintaining solid attachment for mid-sized cells. It suits performance-focused projects where weight matters.
Why chosen: Aluminum construction offers a balance of strength and weight, suitable for performance-oriented builds where throttle response and handling may be influenced by under-car weight distribution.
Buying Guide
What to consider when choosing a fuel cell mounting kit
- Fuel cell size and shape: Ensure the kit supports your exact dimensions, especially width and height, to avoid interference with vehicle components.
- Material and finish: Steel offers rugged strength; aluminum reduces weight; powder coating or painting increases corrosion resistance and blends with the vehicle’s color.
- Installation method: Some kits are direct-fit with no modifications, while others require welding, trimming, or custom fabrication.
- Hardware inclusion: Confirm whether mounting bolts and hardware are included or if you must source them separately.
- Compatibility with mounting surface: Consider space under the tank area, clearance for hoses, and potential interference with exhaust or fuel lines.
- Future upgrades: If you plan to upgrade the fuel cell size later, choose a mounting system with adjustable or extra-wide fitment.
How to compare options effectively
- Best for wide cells: Look for kits advertised with large dimensions or universal mounting brackets.
- Best for factory-style installs: Direct-fit, OE-replacement kits simplify installation and maintain original aesthetics.
- Best for weight-conscious builds: Aluminum or lighter mounting solutions reduce overall vehicle weight.
- Best for severe-duty use: Heavier steel constructions with reinforced plates suit off-road and high-vibration environments.
Quick decision checklist
- Do you need a bare-metal finish or a pre-coated option?
- Is there a specific fuel cell model you must accommodate?
- Will you perform the installation yourself or hire a shop?
- Are there space constraints in your under-tank area?
FAQ
- What size fuel cell can I mount with these kits? Most kits support common sizes from 12 to 17 gallons, with some designed for up to 20 inches in width. Always verify your cell’s measurements and mounting hole pattern.
- Do these kits include mounting hardware? Several kits specify that bolts are not included, while others include mounting hardware. Check the product details for your chosen item.
- Is powder coating or painting required? Some kits ship bare metal and require paint or powder coat before installation to prevent corrosion.
- Can I mix and match mounting brackets with different fuel cells? Compatibility depends on hole patterns and dimensions; confirm with product specs before mixing parts from different kits.
- Which kit is best for a factory-like appearance? Direct-fit OE replacement kits are designed to replicate factory mounting and provide an authentic look.
- What installation considerations are important for off-road use? Opt for heavy-gauge steel or reinforced mounts with minimal flex to resist vibration and jolts from rough terrain.
