The best marine fuel tank pickup assembly depends on tank depth, connection size, and whether you need a flexible or rigid tube. The Sierra 22-inch assembly is best for buyers needing a longer flexible pickup; the DEF tube offers an adjustable rigid option; and the 12- and 24-inch Replacement Kits tubes provide fixed-length choices. Check thread measurements and tank dimensions before selecting any replacement.

| Replacement Kits 12-inch | Shorter fixed pickup | Barb adapter included |

| SADIFOKPLY 12-inch | Pickup with check valve | Rigid tube with strainer |
Sierra 635021-10 22-Inch Flexible Assembly
This Moeller-branded Sierra assembly is a flexible fuel pickup with a listed length of 22 inches. Its flexible construction distinguishes it from the rigid polyethylene tubes in this comparison. It is best for a buyer whose existing assembly calls for a flexible pickup and whose measured tank depth suits a 22-inch part.
The product is selected for its longer stated length and flexible design. Its listing describes precision construction but does not provide thread dimensions or additional material details. Confirm the connection type and required installation dimensions before ordering; the listed length alone does not establish fit for every tank.
DEF Adjustable Polyethylene Pickup Tube
The DEF tube is a rigid polyethylene fuel withdrawal tube with a strainer and adjustable length. The provided specifications list a 3/8-inch NPT external thread and a 1/4-inch NPT internal thread on a 90-degree aluminum joint. Its material and listed E10 and E85 compatibility make it a useful option for buyers seeking an adjustable rigid assembly.
Choose this model if adjustability is more important than selecting a fixed 12- or 24-inch tube. The product information does not clearly state the adjustment range, so check that range and the fitting arrangement with the seller before purchase. Do not assume that “universal” means it matches every tank opening.
Replacement Kits 12-Inch Pickup Tube
This fixed 12-inch tube is made from high-density polyethylene and is listed as resistant to corrosion and compatible with E10 and E85 fuels. Its connections are specified as 3/8-inch NPT external and 1/4-inch NPT internal. A brass barb adapter with a 1/8-inch NPT thread and 1/4-inch inside-diameter outlet is included.
It is best for buyers who need a shorter fixed pickup and want the listed adapter included. The manufacturer identifies it as a replacement for part 7-0948. Its 12-inch length may not suit deeper tanks, so compare the tube depth and fitting requirements with the original assembly before choosing it.
Replacement Kits 24-Inch Pickup Tube
This 24-inch version has the same stated high-density polyethylene construction, corrosion resistance, and E10 and E85 fuel compatibility as the brand’s 12-inch option. It also lists 3/8-inch NPT external and 1/4-inch NPT internal threads, plus a brass barb adapter with a 1/8-inch NPT thread and 1/4-inch inside-diameter outlet.
It is best for buyers whose tank requires a longer fixed tube and whose connection dimensions match the listing. The length is the main difference to compare with the 12-inch model. Avoid choosing it solely because a longer tube seems preferable; verify tank depth and required pickup position first.
SADIFOKPLY 12-Inch Tube With Check Valve
This rigid 12-inch pickup tube is made from high-density polyethylene and is listed as compatible with E10 and E85 fuels. The product title specifies a strainer and a 0.31-inch, or 8 mm, check valve. The listing describes the valve’s purpose as allowing one-way flow and helping prevent backflow.
Choose this model if a check valve is a required feature of the replacement you are seeking. It is also listed as replacing part 7-0948. The supplied product details do not specify the thread sizes, so verify those dimensions before buying rather than assuming they match another 7-0948-style tube.
Buying Guide: How To Choose A Marine Fuel Pickup Assembly
How long should the pickup tube be?
Measure the original assembly and the tank’s internal depth before ordering. Compare the needed pickup position with the listed tube length, not just the tank’s overall height. The products here range from 12 to 24 inches, while the Sierra assembly is listed at 22 inches. A length mismatch can prevent a suitable fit.
Should you choose a flexible or rigid tube?
A flexible assembly, such as the Sierra model, differs in construction from rigid polyethylene tubes. Choose based on the design of the part being replaced and the available space inside the tank. The DEF option is adjustable, but its stated adjustment range is not provided, so confirm it if that feature matters.
Which fittings and fuel details should you verify?
Match thread type and size, outlet dimensions, and any barb adapter to the existing fuel system. Several products list 3/8-inch NPT external and 1/4-inch NPT internal threads, but not all listings provide the same details. Check fuel compatibility in the product information and confirm that the selected assembly suits the intended application.
- Measure the original tube and tank depth.
- Confirm NPT thread sizes and outlet dimensions.
- Check whether a strainer, adapter, or check valve is needed.
- Compare the replacement part number where the listing provides one.
Frequently Asked Questions
What does a marine fuel tank pickup assembly do?
It draws fuel from inside the tank through a pickup tube and into the connected fuel system. Some listed assemblies include a strainer or check valve.
Are all 7-0948 replacement tubes interchangeable?
Not necessarily. Listings may share a replacement part number but differ in length, fittings, or included features. Verify dimensions before ordering.
What is the difference between a 12-inch and 24-inch pickup tube?
The stated tube length differs. Select the length that matches the tank and required pickup position, after measuring the existing assembly.
Do these products list E10 and E85 compatibility?
The DEF, Replacement Kits, and SADIFOKPLY listings specify E10 and E85 compatibility. Check the individual product details for any model not listed with that information.
