Fuel pump could make noise and be heard.

I m not entirely sure where the noise is coming from, the claim about it being from the oil pump was not directly from Stillen, myself and others here at the shop have been investigating this noise whenever it arises. We have installed numerous oil cooler kits with both SS and the Aeroquip Socketless Hose. For some reason, the SS line, even when insulated with either a rubber heater hose or a matching ID Silicone hose, seems to still generate the whining noise.
We had one customer come back and actually make the swap to the socketless line since it seems to completely eliminate the sound all together.
