I have a 6.6l 401 in my 88yj and im done with the carb iim getting a fitech 600hp fuel injection system...you know the bolt on units that look like carbs,anyway it needs 65 psi running to it and the in tank pump wont put that out,I believe it runs up to 45 psi.
so my question is if there is anyone who has retrofit a higher pressure pump in place of the stock one or put in an inline and how did they do that.
it had the 2.5l in it before the swap so im not sure if I need return lines or a reg I believe it has a return already.
