Engine/Transmission (1998.5 - 2002) Vulcan lp relocation kit

[RHerrmann]

Well its that time again, fp drops to 5-8 psi. And of course I'm getting ready to leave for the long weekend. Have to try to get the truck in to a shop before thursday.

Was wondering what kind of luck those of you with a Vulcan lp relocation kit were having ? Is your pump lasting any longer ? Is it easy to change ?

I'm pretty sure the heat killed mine. As soon as the outside temps went up my fp went down. maybe keping the pump out of the engine bay away from heat and vibs. will help it last more than 1. 5 yrs.

When my LP started cavitating and dropping PSI recently, I tried several things - but the final one that so far has totally cured the fluctuating PSI was relocating the stock LP down on the frame rail back near the pusher that has been effectively taking over where the stock LP gave up.



Still using the same LP, just relocated, and that completely ended the cavitation and erratic PSI.



Good luck with yours.

I "home brewed" a Vulcan kit several years ago before the kits were available. The truck has 148k miles on it... on only the second lift pump! I think the Vulcan kit would be a good investment.

Vulcan Kit

I have a 2000 six-speed one ton with 16,000 mi. Thought I would not have problem with transfer pump but I did with 7 psi and the the big o psi and then back to 5 psi. Put new transfer pump from Cummings and relocation kit and pressure is 14 psi on low end and +15 psi on high side. Even with the new 7 micron fuel filter no problem. I did not remove original pump just put new one in front of fuel tank. joe z

I just finished installing my Vulcan LP Relocation Kit a couple of hours ago. Great kit, comes with everything you need and fairly easy to install. I had to replace my LP, as it was dead, so decided to relocate it while in the process. Results, 16 psi at idle and 14 psi @ full throttle with a load.



FYI- if you decide to install the kit youself, try to have the fuel tank near empty. when I cut the line back by the tank, it started a syphon and made one giant mess. Had to grab the air gun and blow back into the line to stop the syphon. The garage will smell like diesel for a while, Oh well.

Hey guys, anyone install this kit on a short-bed quad-cab? I just finished up the install over the weekend and ran into a "problem". There are three fuel line clips on the short-bed - one about 6" forward of the tank, one about 2" forward of the crossmember, and one for where the lines become flexible at the front of the frame.



From the instructions, I thought the best location would be the one closest to the tank but there doesn't appear to be a good way to cut the lines far enough back to accomodate the bend the new fuel line needs to make to transition out to the pump on the bracket. So, I mounted it in the "middle", right next to the cross member. The only "problem", is that the weld bead on the frame rail next to the bracket causes the bracket to no sit level. I was going to cut a relief in the bracket but it appeared that it would have to be pretty severe for the bracket to sit level. So, I just figured it being off level isn't that big of a deal and finished the install.



Anyone have any problems with leaks? I have a couple slow ones that appear to be at the -AN fittings... didn't want to tighten them too much but it seems I may not have them tight enough.



Any feedback is appreciated.



Thanks,

John

One thing that keeps running through my mind is the ID of the fittings in the Vulcan kit. I bought my fittings from the Parker Store, and they had fairly small center holes. I drilled out everything to a minimum 5/16 ID. Before you install the kit, would some of you guys grab a drill bit and see what size the center hole is on the fittings in the Vulcan kit?



Thanks.

Steve,

I measured the fittings in the Vulcan kit that replace the Dodge banjo fittings and they measure . 295" id, the rest of the fittings measured . 390" id. Hope this helps.

I'm working by memory here... I don't have a fraction to decimal conversion handy, but I think the . 295 is a little smaller than 5/16. If you are not afraid of it weakening the fitting too much, I would recommend drilling them out to a FULL 5/16 MINIMUM... more if you think they will stand it! What is the point of big 1/2 inch lines with restrictive fittings!!!

if you get the kit directly from vulcan it has the big fittings. mine did anyway. i have heard genos kit uses smaller lines. i never seen their kit though i may be wrong. mines 3/8 id

What I put together is 3/8" line/fittings. I didn't see a point in 1/2" line since the lines to the tank are only 3/8. It's not going to flow any better IMO... well maybe a little bit, but it would have taken more adapters and been more money.
