Since Im a 24v guy (not for long) what the heck is a delivery valve and where is it, in the pump? I hear of 181-191ect what do those #s mean CCs? Also were the 98 5speeds 215 or 235hp?

dv's are inside the injector pump very easy to change in about a half an hour. if you look at the pump you see 6 metal fuel lines coming out of it going to the injectors. remove the lines and then you need a special socket to remove the barrels and the dv's just sit right underneath there. 181's come stock in the 180(96-97 autos) and 215 pumps(96-98 manuals)), 191's are an upgrade, but if you want some real power get a set of laser cut dv's. dv's limit the amount of fuel sent to the injectors
