Frequently Asked Questions
Does the Pump Require Any Special Tools for Removal or Installation?
No; the pump generally requires no special tools for removal or installation. The description notes typical installation challenges are minor, with standard hand tools sufficing, though service manuals and basic diagnostic tools are recommended.
Is the Pump Compatible With Diesel Engine Variants?
No; diesel engine compatibility is not indicated. Independent pump performance analysis suggests the Dorman 310-233 targets gasoline evaporative systems, so buyers with diesel variants should verify OEM specifications or consult support before purchase.
Can I Use This Pump With Aftermarket EVAP Components?
Yes; the pump can work with aftermarket compatibility when the evap system fittings, port sizes, and electrical connections match OEM specifications. The user should verify inlet/outlet flare sizes, mounting, and EPA compliance before installation.
What Is the Expected Electrical Current Draw During Operation?
Like a pocket watch ticking, the answer: the pump typically draws about 1–3 amps during operation. The response cites current specifications and electrical efficiency, indicating modest load consistent with small EVAP leak detection pumps.
Are Replacement Hoses or Fittings Included With the Pump?
No, replacement hoses or fittings are not included; the pump ships alone. The manufacturer recommends consulting the installation guide for compatible replacement parts and installation procedures, or contacting customer service for parts and warranty assistance.
