for Chevy BISCAYNE 1969-1972

When the mechanical fuel pump leaks oil from a silicone gasket, the cause can often be traced back to improperly tightened pump mounting bolts. The fuel pump bolt torque specification is usually around 25 to 35 foot-pounds. Regardless of the model of the fuel pump, the best way to ensure the bolt is tightened properly is to use a torque wrench. To make sure the bolt stays in place, apply a small amount of thread-locking compound before reassembly

Caution:
1.Prohibit fuel pump free working in non-oil situation.
2.Fuel pump in line should use standard fuel:alcohol pump can use alcohol fuel, diesel fuel pump use diesel fuel,methanol fuel pump use methanol.
3.You need replace the fuel pump and strainer at the same time.
4.Replace fuel strainer according to the stipulated time or mileage.
5.Replacement pump should be kept in clean work environment.
6.Oil should be added timely if it is too low, it is recommended to add oil when the t-ank only have 1/3 of fuel.

NOTE: If a new pump works when directly hooked up to 12 volt battery power source, but your vehicle still suffer from no start or low pressure, please check fuse, relay, electrical connector or any other possibility for looseness and burned connector pins.
