Raptor install

[clong1959]

got my raptor 95 installed today took about 8 hrs most time spent on geting stock line of fuel tank and disconecting old pump, arms to big to get in there after over an hour of working on it my son came out with his skinner arms and got it off in about 2 minutes, but the pumps working good 18 lbs at idle and 15 lbs excelerating my old pump was goining bad so im a happy camper now. should be in 2nd gen. thread sorry.

Looks like your getting good pressure both ways! Putting mine on was one of the best things I have done to my truck. Having good pressure and knowing that the check valve is opened and cooling the VP is a good feeling!

Big Grin... I'm sure you VP44 is going be much happier and perform better...

Just got my Raptor 100 on last night. I bagged the ends of the old system, but left it in place. The old pump was acting up, but hadn't quit yet, It should be easy to reconnect the 2 ends, and the electrical plug if the raptor should ever quit. (I love redundancy) After 10 minutes idling to purge the new system, I changed out the old fuel filter. Fuel pressures was only showing about 15 psi. Took it for a test drive. Pressures quickly dropped to <10 psi during acceleration. Came Home. Turned regulator up to 18 psi, Pressure still dropped quickly. Turned regulator up to 22 psi, Pressures never dropped below 17, Backed Pressure down to 20 psi even. Now pressures only drop to 15...13 if I'm really hard into it. Question is...Is 20 psi at idle a good pressure to run? I keep seeing 18 psi max in posts, but I don't like the large drops I'm seeing at that pressure. 20 psi seems to be giving me more consistent pressures. I just don't want to risk any IP damage.Question 2...I didn't change the line from my stock fuel filter to my VP44. My fuel pressure sender is connected at my VP44 inlet via a 16" grease gun hose. Could the small line, and banjo bolts be causing the pressure drops at 18 psi and below?

should do no harm...but i would lower it to 17 or 18

yes. the banjos have are very small passages. you should do 3/8" (or even 1/2") fuel hose for the system. your pressure loss will be less

The banjos on the line between the stock lift pump and the stock filter housing need help because, while the barb is 5/16 on the outside, the hole thru it is LESS than 3/16.

i have Universal Big Line Filter to Injection Pump Kit w/ fuel pressure access

Guess I need to update my signature line.

Are you running 1/2" linesfuel thru that?On my truck I am. Set the regulator to 18 psi. It drops to about 15 if I romp on it. from the tank to the filter? Do you have an intank pump and running the

fuel thru that?

Neither did I. I have mine running from the top of the fuel filter. I used all of the fittings that came with my set up. The only banjo bolt that I didn't change was from the filter to the VP.

I believe that they changed fuel filter in 99, or 2000. It shows the older style with both the inlet and outlet lines at the top of the filter. On mine, the inlet is on the rear to the filter, and the outlet is on the bottom. You change the filter from the top.
