6 Best Fuel Pickup Tubes For Custom Storage Tanks

When a tractor dies in the middle of a planting run because of a clogged or failed fuel pickup, the loss of time and momentum can derail an entire afternoon. Reliable fuel delivery is the backbone of any well-run hobby farm, yet the pickup tube inside a custom or auxiliary tank is often the most overlooked component. Choosing the right hardware ensures that the engine stays fed even when the tank runs low or the terrain gets bumpy.

Dorman 55201 Nylon Kit: Best Universal Solution

The Dorman 55201 is the go-to for those who need a reliable, no-fuss fix for standard fuel systems. Its flexible nylon construction allows for easy manipulation, making it an excellent choice if the internal dimensions of a custom fuel tank are slightly irregular or difficult to access.

This kit excels in simplicity, providing everything necessary to get a fuel line plumbed without requiring specialized hydraulic tools or complex fittings. It is particularly effective for small-engine equipment or backup generators where high-pressure performance isn’t the primary concern.

For the hobby farmer working on tight budgets and standard gravity-fed or low-pressure systems, this is the most practical choice. It lacks the ruggedness of high-end diesel components, but for general utility on the farm, its versatility is unmatched.

Gen-Y GH-088 Draw Straw: Top Pick for Diesel

When running diesel equipment, air infiltration is the enemy of performance. The Gen-Y GH-088 Draw Straw is engineered specifically to maintain a consistent fuel column, preventing the dreaded air bubbles that cause engines to sputter under load.

This design is a significant step up from universal kits, featuring a rigid construction that won’t collapse or vibrate against the bottom of the tank. It is purpose-built to work with aftermarket lift pumps, making it a favorite for those running high-output diesel trucks or heavy-duty machinery.

If the goal is to eliminate fuel starvation during high-demand tasks like pulling loaded trailers or powering irrigation pumps, invest in this unit. It provides the peace of mind that the engine will draw every last drop of fuel without losing prime.

Allstar ALL10174: Most Durable Aluminum Tube

Aluminum pickup tubes provide an rigidity that nylon simply cannot match, especially in tanks subjected to heavy vibration and rough field conditions. The Allstar ALL10174 is a rugged, permanent solution for those who dislike revisiting fuel system repairs.

Because it is made from high-quality aluminum, this tube resists the degradation that occurs over years of exposure to ethanol blends or modern additives. It is intended for custom racing setups but fits perfectly into the DIY fabrication of auxiliary tanks for UTVs or small fuel trailers.

Choose this product if the fuel tank is mounted on a piece of equipment that sees frequent washboarding or off-road use. It is a set-it-and-forget-it component that favors long-term durability over ease of installation.

Fass STK-1002 Kit: The Easiest Installation

The FASS STK-1002 kit is designed for the operator who wants a professional-grade fuel system without spending all day bent over a fuel tank. Its strength lies in the bulkhead fitting system, which creates a secure, leak-free seal with minimal effort.

This kit is designed specifically to integrate with high-performance lift pumps, making it a staple for those who maintain large diesel equipment fleets. The instructions are clear, and the components are engineered to fit together with factory-like precision.

If the farm schedule is packed and there is no room for trial-and-error, this is the superior option. It is more expensive than universal alternatives, but the time saved during installation and the reliability of the seal make it a wise investment.

XDP Diesel Sump Kit: Best for Bottom-Feeding

Bottom-feeding sumps, like the XDP Diesel Sump Kit, address the fundamental issue of fuel starvation by drawing from the absolute lowest point of the tank. By gravity-feeding the fuel system, this setup ensures that even when the tank is nearly empty, the engine never runs dry.

Installation involves cutting a hole in the bottom of the tank, which requires a steady hand and proper sealing techniques. However, the performance benefits—consistent fuel delivery and reduced strain on the pump—are significant for high-hour machinery.

This is the right choice for anyone who frequently pushes their fuel supply to the limit during long work days. Just ensure the tank area is clear of frame obstructions before cutting, as the location is permanent once the hole is made.

Universal Stainless Tube: Budget DIY Option

For the farmer who prefers fabricating from scratch, a universal stainless steel pickup tube is the ultimate base component. Stainless steel offers excellent corrosion resistance and can be bent or cut to fit almost any custom tank configuration.

While it requires more labor—including drilling, tapping, and securing the fitting—the ability to customize the length and angle is a distinct advantage. It works well with AN fittings, allowing for a professional, leak-proof fuel circuit at a fraction of the cost of branded kits.

Use this option only if there is access to basic shop tools and a comfort level with plumbing fuel lines. It is the perfect solution for unconventional storage tanks where pre-packaged kits simply will not reach the bottom corners.

Choosing Your Pickup: Material and Size Guide

Selecting the right material comes down to the fuel type and the tank’s environment. Aluminum is excellent for structural integrity, nylon is best for flexibility and vibration damping, and stainless steel is the gold standard for long-term chemical resistance.

• 1/2 inch or 5/8 inch: Standard for high-flow diesel systems.
• 3/8 inch: Typical for gas-powered engines and smaller tractors.
• 1/4 inch: Sufficient for small lawn equipment or light-duty generators.

Always match the tube diameter to the pump’s inlet size. A line that is too small will cause the pump to cavitate, while one that is too large may introduce air if the seal isn’t perfectly tight.

Proper Installation in a Custom Fuel Tank

Installation begins with cleaning the tank interior thoroughly. Even a small metal shaving left over from drilling the tank entry point can destroy a fuel pump or clog an injector down the line.

Always use a fuel-rated sealant or gasket on the bulkhead fitting where the pickup passes through the tank wall. Double-check that the tube is long enough to reach the bottom but angled or cut at the tip to prevent it from suctioning against the tank floor and starving the engine.

Secure the line to the tank exterior with high-quality clamps. Vibration is the primary cause of fatigue and leaks; reducing the movement of the fuel line at the tank junction is critical for long-term success.

Pickup Tube Placement to Avoid Fuel Starvation

The most effective placement is near the center or the lowest point of the tank, accounting for the natural pitch of the equipment. If the tank is on a slope, the pickup tube should be positioned toward the rear to ensure that as fuel moves, it remains submerged.

Avoid placing the pickup too close to the fuel return line. If the warm fuel returning from the engine is dumped directly next to the pickup, it can lead to aeration and reduced efficiency.

Maintain at least a half-inch clearance between the end of the tube and the bottom of the tank. This provides enough space for fuel to flow freely while keeping the intake away from the sediment that inevitably settles at the bottom of fuel tanks.

Safety First: Handling Fuel and Tank Fittings

Safety is not negotiable when modifying fuel systems. Before drilling or cutting any tank, ensure it is completely purged of vapors; even an “empty” tank can hold enough fumes to ignite during a spark-inducing cut.

Use non-sparking tools whenever possible and keep a fire extinguisher within immediate reach. Always verify that all fittings are compatible with the specific fuel type being stored, as gasoline and biodiesel react differently with various rubber compounds and sealants.

Periodically inspect the fuel line connections for signs of weeping or cracking. A well-installed pickup tube is a vital part of a sustainable farm infrastructure, but constant vigilance ensures that the farm stays productive and fire-safe throughout the season.

Proper fuel delivery is the lifeblood of a working farm. By selecting the right pickup tube and ensuring a clean, secure installation, you minimize the risk of mechanical failure and keep your equipment running reliably throughout the peak seasons.
