Are these hard to install I want to gain fuel mileage and power the raptor fuel pump I want is the 100 gph how much horse power are these good for I would do the 150 but don't want to mess with the draw straw the edge I want is the juice with attitude to monitor egt fuel pressure and tranny temp will this work for me I eventually want to do ddp injectors probably around 100 125 when I bought the truck I was told it had 75 HP injectors and it does have 4 in down tube with 5 in straight exhaust but I really need to do a fuel pump soon side note had tranny checked it had been rebuilt some time and has a shift kit nothing else is known thanks in advance sorry about the long post

They are a pretty easy instal and that 100 should do just fine but yo dont have to do a draw straw with the raptor 150 either.
