You will want -06 male AN to NPT. This will let you add a NPT tee for a pressure gauge and give you a choice of NPT to barb fittings for fuel line connection. You'll have to borrow the o-ring from the included fitting for use on the new ones. If you are using stock injectors, you may want to get the optional "hard" spring to go with the S-FMU. This lets you get as high of a idle pressure as you want. The optional bleed valve can be useful too, for fine tuning the fuel curve. Vortech often denies the existance of the third spring and bleed valve. The spring is 7X100-050.
