Engine/Transmission (1998.5 - 2002) relocating LP very worthwhile

[Sageair]

I recently relocated my dying LP using the Vulcan kit. I was hoping to get a bit more out of the ailing old LP but I did have a new spare in the truck. On a trip to Boise Saturday the old pump packed it up forcing me to replace it along side the road. I had prepared for this by buying two cheap Visegrip spinoffs to pinch off the fuel lines $12. 50. I had some cheap nut drivers needed for the hose clamps and a bargain bin 13 mm wrench for the lp nuts

$ 4. 00. Total time to change LP, 7 minutes. Priceless

Sounds good to me. BTW, how much for the spare pump? So, is that the whole tool kit needed for the job? I gotta get me one o them.

 

[Sageair]

The Vulcan kit was $89. 00 which includes everthing to get rid of all the banjo fittings from fuel tank to VP and to relocate the pump. The beauty of this is you can do it in a warm garage at your leisure instead of fighting the old location on a dark night with cold hands. I paid $160. 00 for the spare lift pump off ebay. But yes to change the lp now all thats needed is the nut drivers for the clamps. A screwdriver will of course work but nut drivers are so much nicer to use. The visegrips are not absolutely necessary but they allowed me to do the change with only a small amount of diesel getting on my hands and none on my clothes. The last thing needed is the 13 mm wrench. Sweeeeeet! PS the lift pump holds a surprising amount of fuel. Drain it carefully or youll get diesel where you probably don't want it. Steve

What's your fuel pressure now with the vulcan kit? was there any improvement other than access?

 

[R-N-R]

A kit like Vulcan's will typically enable steady pressure more so than increased pressure. It is common for larger injectors and/or a fueling box to drag pressure down to dangerously low levels on a stock fuel system. I also believe that a kit like this will provide increased flow which is a benefit to the VP44. The Vulcan kit seems to be one of the best values currently on the market.

the main benefits are:

1 relocation of the pump to a more sensible spot( so it pushes fuel, not pull)

2 removal of the restrictive banjo fittings



as RNR stated, your peak pressure should be around the same, but it should be more stable and not draw down as low WoT

I've elected to keep my LP in the stock location. All I've done is open up the lines with Scotty's Smart Fuel kit.

LP is going strong and give plenty of pressure. I'm getting 16-18 idle (depending on outside air temp), 13 cruise, and 9 WOT.

This is with stock LP MAD ECM and Mach 4s.

I'm happy with the current setup.

What does Scotty's smart fuel kit consist of and where can it be got?

I don't have a fuel pressure gauge only the low fuel pressure LED which activates at 5 p. si or below. I can only tell you that under no circumstances can I pull the fuel pressure down to 5 psi.

My light never came on this summer either. However, my check engine light did come on and Dodge replaced my lift pump because of low flow. (Also the VP-44)

Sageair, just wondering if you considered an inline ball valve between your lp and the tank? This would allow you to secure the fuel supply to the lp and avoid crushing the fuel line with the "vise grips" if/when the need arises to change out the lp? Just a thought.

Hi guys,

I'll jump in here and say that I too have just recently installed the Vulcan kit. Awesome kit.



As far as fuel pressures, it didn't raise the pressure at idle but what it does do is keep the truck from dragging down the FP when I'm on it.



I have between 14. 5 and 15 lbs at idle

12. 5 at 60mph

and to date haven't been able to drag it down below 12lbs no matter how hard I'm into it.



Interesting idea about the fuel shutoffs vs. visegrips. Either way, the kit makes it really easy to change the LP.
