i just bought a brand new msd inline fuel pump. it didn't come with instructions and from the power and ground connections there is no indication of which is which. can anybody help me out on this.

 

look at the pump, there should be a marking of arrow indicating flow of direction....

double check the polarity of positive and negative

cut your fuel lines between the fuel filter and the fuel rail..and install the fuel pump there

i seen the arrow for the direction of flow. but the thing i'm having trouble with is the polarity of the terminals. there is no red or black marks or +/-, nothing. i don't knoow which one to run to the ground and which one to run to the ignition. anybody hooked up one of these before?
