Considerations: verify system compatibility, note exclusion from U.S. use, assess hose flexibility, and monitor for wear.
Installation and Maintenance
A single straightforward replacement or new installation usually takes under 20 minutes with basic hand tools; the Attwood 93038AI7 primer bulb is compact (5.5 in long, 1.25 in diameter) and fits 3/8 in fuel hose, so measure hose length and routing before beginning. The installer is advised to follow installation tips: confirm barb orientation, use stainless clamps, avoid sharp bends. Maintenance schedule: inspect monthly for cracking, every season replace if stiff.
| Task | Frequency | Notes |
|---|---|---|
| Visual inspect | Monthly | Check leaks, flexibility |
| Clamp torque | Each install | Tighten snug, avoid overcrimp |
| Full replacement | Seasonal | Replace if aged |
| Leak test | After install | Prime and observe |
Safety and Compatibility
Because proper fuel handling affects both performance and safety, users should confirm that the Attwood 93038AI7 primer bulb is compatible with their system before installation.
The review notes fuel compatibility: alcohol resistant, accepts leaded and non-leaded fuels, not for use in the U.S.A.
Safety guidelines include inspecting for leaks, securing stainless steel clamps, and replacing bulbs showing stiffness or cracks.
Q: What sizes fit common rigs?
A: Barb ends suit typical 3/8″ or 1/4″ hoses—measure before purchase.
Practical steps: verify hose ID, confirm flow direction via double check valve, follow torque and clamp recommendations for secure, leak-free operation.
Frequently Asked Questions
Can This Primer Bulb Be Used With Diesel Fuel?
Yes. He notes diesel compatibility is not specified; the bulb is alcohol resistant and for leaded/non-leaded fuels, so diesel compatibility should be verified with manufacturer to avoid reduced fuel efficiency or material incompatibility and guarantee safe operation.
What Is the Expected Service Life Under Normal Use?
Approximately 12–36 months of service longevity is typical under normal use. The responder advises periodic inspections, follow usage recommendations for fuel compatibility, replace at first signs of deterioration, and guarantee clamps and hoses remain secure for safety.
Are Replacement Bulbs and Clamps Sold Separately?
Yes. The seller offers replacement bulb compatibility listings and separate clamps; purchasers should verify clamp durability specifications and hose diameter match. Replacement parts are sold individually to guarantee proper fit and long-term serviceability.
Does It Fit All Standard Fuel Hose Inner Diameters?
No; it does not guarantee universal fit. The responder notes fuel hose compatibility depends on specific barb dimensions and standard sizing; users should verify inner diameter match and use appropriate clamps for secure installation.
Is There a Warranty or Manufacturer Support Available?
Like a lighthouse guiding mariners, the company typically offers limited warranty details and manufacturer support; the user is advised to consult the seller or manufacturer website for exact warranty details, coverage periods, and available manufacturer support options.
