LS1 fuel line & pump expeirences / ?'s
For those of you with modified LS1 engines, did you need to change your fuel pump or system? how much power can the stock unit support? anyone running 500+HP/ 600TQ on a stock unit? If the pump was changed, did you increase the size of the lines?
Although the stock ports measure 3/8" OD, there are about 1/4" ID whereas a steel 3/8" OD line is about .33" ID.
