Product Questions Answered by Jim. the Pressure Washer Expert
What replacement pump would I get for a Troy Built (020344) power washer.? 2800 psi
Bruce

What replacement pump do you recommend for my Gas powered Huskey Pressure washer. The original pump is a 2.3 GPM / 2600 PSI pump. And it is attached to a vertical shaft Honda motor. Will the AR 2800 PSI 2.5-GPM 7/8" Hollow Shaft Vertical Replacement Pressure Washer Pump w/unloader fit this? Also is this a better quality pump than the one it originally came with? The one it came with worked perfect three times and never worked again. I do not need another like that! Thank you.
