When doing a LS swap into a 94 civic ej 1.6vtec do most people use the 1.6vtec fuel filter when running a b18b1 or do they carry over the b18b1 fuel filter? It appears my car has the stock 1.6vtec filter running with the LS swap because I purchased a 1.8LS filter and it isn't the same as the one in the engine bay.
