Engine/Transmission (1998.5 - 2002) What type LP is best for the $$$$

[LKothe]

:{ I need a new LP but want to relocate it back to the tank area. I also think I want to remove the "silk" intank strainer and install one that I can open and clean. I cannot afford a $650 Fass, Vulcan etc. so what's the best pump for the $150 range. I've heard really good things about the Holley Blue. Can any of you help me get the ol Ram going again?

The Walbro pump from Glacier Diesel Power costs a little over $100 bucks. You will need some plumbing to hook it up however.

Check out the Glacier pump in my sig. There's pictures of the install in my reader's rig gallery. It's a Spectre filter from Kragen with the passage holes drilled out for extra flow. Cheap, serviceable, visible.



Are you having problems with the fuel pickup? If you're going to the trouble of dropping the tank to take out the strainer, put in a Draw Straw. I'd do it if/when I do it again.



As for the $$ problem, throw $150 now, $200 later, bada-bing, you've spent a lot more than if you just bite the bullet and do it all at once. Besides, that's what credit cards are for.

Is there some reason to use the draw straw rather than installing a bulkhead in the lower portion of the tank side? I would think that would reduce the suction pressure and make the pump more efficent? Have you heard of anyone doing that?

What size tube is the Draw Straw II?

You have a very nice installation. What is the hose just above your pump. Is a kick back line required to the tank since the pump can put up 90+? Also reading about the Glacier kit, it has fittings for a by pass, why? Thanks, Larry

Hi Mike, thanks for the reply. The Walbro looks like a nice pump to install. Fittings, hose and stuff are no problem. I'm just wondering if I should install a relay controlled by my old pump wiring and a new hot wire to the new pump? Do I need a by pass or anything like that? Thanks, Larry

Sounds like a lot more work than a Draw Straw, and I'm unsure of any advantage... the Draw Straw is 1/2" and fits right into the grommet in the top of the pickup assembly. You asked about the Draw Straw II. Do you have an in-tank LP?

Exactly, it'll produce 90+, which would be way too much for the VP. Richard has fabricated a simple little bypass valve that can be adjusted easily by adding or removing shims. Comes set at 20 psi, removing shims lowers system pressure. Glacier's setup comes with everything you need, fittings, hose, mounts, relay, wiring, detailed instructions, and Richard's top notch customer service. I've called him and was forwarded to his cell phone.



Running derated like that makes the Walbro a pretty dependable setup, and a prefilter just adds to the dependability... . but this is a Dodge. Keep some tools, wire, and duct tape under the back seat. And a blanket. :-laf

You have to install a regulator and fuel return. The Walbro pump puts out too much pressure to run without a regulator. The return is to bleed off the excess pressure the regulator relieves and return it to the tank. Let me kmow if I can help. I carry two walbro kits that are a great bargain.

What they said! The Walbro puts out way too much pressure.

Not sure how much you are willing to spend, but my set up seems very good. I have about 4k on it so far.



Vulcan Big Line Kit

Vulcan Draw Straw

Glacier Walbro GSl-391

Mallory 4307M



The GS-391 uses 3/8 hose, so the Geno's 3/8 big line kit would likely also work if you don't want to buy some adapters.

Jim, Why the Walbro 391 "and" the Mallory. My system is a mix of Vulcan/Glacier also. The VP might still fail... but not for lack of fuel!

$4000??



The Mallory's a regulator, right? There was a post a while back from someone using the Mallory in a redundant system, i. e. still used the Carter with the Walbro.

Shouldn't push more than what the system is capable of. They say the pump is capable of pushing 90psi, but they have it tuned way back so longevity is not an issue. You wouldn't want to run 90psi in the fuel system, as you would blow out seals on the VP. If you check out the full Glacier Diesel website, the 392 pump only runs at 15% of capacity, which calculates out to 19. 5psi, which shouldn't cause issues with our fuel systems.

I know! I was making a reference to the two post above mine that pointed to the need for a bypass in the Walbro system. Walbro provides too much pressure and needs to be regulated down to 15-20psi.

Mike;



My initial intention was to do a mechanical lift pump installation. I already had the Mallory to do that and Richard (Glacier) did not have any regulators that he could sell me seperate from his kit. I wanted to keep the VP supply pressure in a more normal range. The Mallory seems to work very well.

Sorry, 4000 miles... ...



Yes the Mallory is a regulator, its a multi port re-circ type.



I am not sure if I am the one you are referring to, but I have plumbed in a Carter pump in my fuel system to act as an installed spare. Normally the Carter does not run, just sits there. All I have to do is swap the power lead and change the position on a couple of valves and I am back on the road if the Walbro dies. For the little added cost, since I already owned the Carter, my piece of mind is greatly increased. This is likely overkill for most.



Another TDR thread along these same lines with pictures (may load slow). Pictures of my set-up are on the second page.

Yep, you're the one... glad to see it's working well for you
