Why does my SealMaster CRACK PRO 125 diesel burner have low operating PSI?
- JJames RodgersAug 5, 2025
A low operating PSI in your SealMaster Construction Equipment diesel burner could be due to several factors: * The pump might be worn (check and replace). * The fuel line could be plugged (clean or replace). * The pump coupler might be broken (replace coupler). * The burner motor could be worn (replace motor).
