Description

15C-51 Tillotson OEM Fuel Pump Body Screw – Standard Volume (Single Stack)


Genuine OEM | For Single Stack Gas Plates | 0.810" Length

The Tillotson 15C-51 Fuel Pump Body Screw is a genuine OEM fastener designed specifically for standard volume fuel pump plates—commonly referred to as Single Stack or Gas Plate carburetors.


This screw is shorter than the high-volume (Double Stack / Alky) fuel pump screws, making it the correct choice for standard volume(single stack) carburetors.


Key Features:

  • OEM Tillotson Part #15C-51
  • Designed for Standard Volume / Single Stack / Gas Plate setups
  • Not compatible with Alky / High Volume (Double Stack) configurations
  • 0.810" overall length
  • Durable steel construction with proper thread pitch for Tillotson bodies


Important Usage Notes:

  • Six screws are used to secure the fuel pump plate to the carburetor body.
  • These screws are not compatible with high-volume carburetors or those using double stack (alky) fuel pump plates.
  • If you're using a linkage bracket, this screw may not be long enough. Always use screws included in our linkage kits when applicable.


Caution When Installing:

The carburetor body is made of soft aluminum. Over-tightening these screws can strip the threads and permanently damage the body.
Tillotson does not sell replacement carburetor bodies, so if the body is damaged, you'll need to replace the entire carburetor.


Bolt Length:

0.810 inches
(Verify thread engagement and torque during installation)


Ideal For:

  • Rebuilding Standard Volume Tillotson HL Series Carburetors
  • Replacing worn or damaged stock fuel pump screws
  • Single Stack (Gas Plate) setups using pump brackets without added thickness


Does NOT Fit:

  • High Volume (Double Stack / Alky) Tillotson carburetors
  • Carburetors with aftermarket linkage brackets (without longer screws)




FAQ

Q1: What is the 15C-51 screw used for?
A: It secures the fuel pump plate to the carburetor body on standard volume (Single Stack / Gas Plate) Tillotson carburetors. Six screws are typically required per carburetor.


Q2: Will this screw fit high-volume (Double Stack or Alky) carburetors?
A: No. This screw is shorter and will not work with high-volume setups. Use the correct longer screw designed for Alky or Double Stack configurations.


Q3: How long is the 15C-51 screw?
A: The total length is 0.810 inches. This is standard for OEM gas plate (Single Stack) carburetors.


Q4: Can I use this screw with a linkage bracket?
A: Not recommended. Most linkage brackets add extra thickness. This screw may be too short to provide safe thread engagement. Use screws included in our linkage kits.


Q5: What happens if I over-tighten this screw?
A: You risk stripping the threads in the carburetor body, which is made of soft aluminum. Tillotson does not sell replacement bodies, so you would need a full carburetor replacement.


Q6: Is this a genuine Tillotson OEM part?
A: Yes, this is an authentic OEM Tillotson screw, part number 15C-51—not an aftermarket substitute.
