Airtex fuel pumps make the same amount of fuel pressure with being a cheaper pump by having the electric motor spin faster, the faster the fuel pump motor spins the faster it wears out and higher chance of failure. factory or higher quality pumps have better designed internals allowing for lower fuel pump RPM's. Longer fuel pump life occurs with slower pump speeds, the original lasted this long how long do you want the next one to last?
