Hi guys,

I know this topic has been beat to death. But I'm looking for a specific answer.
I recently bought an 02 with 72,000 miles on it. Bone stock as the day it was built. I believe it has the original lift pump on it. I would like to replace it here very shortly. I've been looking very hard at the FASS DDRP. Due to it being a direct bolt-on product. I have enough mechanical ability to change a lift pump, but not so much as to "re-engineer" the entire fuel system.

How many of you have the DDRP in the factory location? Have you been happy with it? I am not doing any other mods except for gauges. NO tuners.

I have one on my truck and it was a breeze to change. The directons said to remove the starter and do it from the bottom. I did mine from the top and did not remove the starter. It only took about 2 hours and I was in no hurry. Some people move it to the frame rail but I put mine back on the block and it bolted right on. LOL

Very pleased with mine also. Relatively easy upgrade and have been running it for almost 3 years. With my edge set on 3 still have adequate pressure. Trans can't take anymore lol. Factory location is perfect for me.

I did mine from the top and only took about 30 minutes. I have since moved it to the frame rail. The pressure has stayed the same. I get 18 psi at idle and 13 at wot.

I did mine from the top. 18 psi at idle , can't pull it below 15 psi at WOT.
This is with RV275 injectors and Smarty on #7.

Not sure about the engineering aspects, but I've been told that the closer the lift pump is to the tank, the better. This is because a pump is meant to push, not pull.

Get the Raptor FRRP. Put one on mine, love it.
