I did yesterday, and it was about 30 minutes, and it was fun knowing i was junking the carter, which was going down in pressure by the day. The instructions included with the DDRP are very clear with pics, and a new 3/8 hose from pump to filter with bigger banjo fittings. Well worth the money. Get it from vulcan, fast shipping and you get 4 year warranty. And you get steady pressure from 15-18 idle, and with edge cranked up, it only drops to 11psi at WOT. And you can always get vulcan relocation kit later to put pump close to tank where all electric pumps are happier.
