With anything, before being scared by failures, the ratio to units sold to units failed must be considered. If one in a thousand units fail, that's still reliable.
Also, in defence of Autotech, they sell just internals and rely on the skills of the person fitting and the condition of the pump being used. Assuming most people build into older pumps, that could explain the higher rates of failure.
However, I will not discredit mass opinion and facts, just like to balance arguements.
And I also don't have any of these items myself so I consider myself non-bias to any company.
