I'm curious, is it possible and if so how would you add additional fuel?

I dont remember there being a return fuel line but i could be very wrong. I have an 88 jeep commanche (2.5 litre) I was just wondering what it would take to do it is all....

 

email me.

 

could you use twin fuel pumps and run an FMU teed into the fuel line? then run a return line like you would for oil?
