my junk has been 119.92 with a mechanical pump, for years i ran 5/16 line and the carter pump. i switched from that to the cv products r5p7 nascar pump (bolts right on a big block with just a touch of clearancing needed) and 3/8 line and didnt gain anything. im just curious if my daughters car will gain any mph with the fuel pump swap. i guess ill see saturday. do you spray your car with a mechanical pump?


I use a stand alone supplemental fuel tank and electric fuel pump to feed the nitrous system. The engine still uses the mechanical pump during the nitrous use.
