Any interest in fuel slosh fixes? 1/4 tank issues?

[Fishin Guide]

Hi guys and gals.



With the success of the Vulcan DrawStraw V, we have pulled out some of our original prototypes and we are gauging interest other similar products.



Obviously, the DSV and it's options covers all the 04. 5 and up and 2nd gens with the in tank retrofit. This system has worked flawlessly thus far. And if anything pops up, we will be sure to tweak it. But the hardest part of this install is getting the old pump out. No parts have to be broken and it is complete. The fuel is drawn from a level as low as the factory pump system and with the various systems, it will work with any pump install. (Depending on options chosen)



Way back in the beginning of the original DS1, which has gone through modifications over time, we had some fittings similar to the DSV and would function in a similar manner. While the actual function of these parts would be no different than the DS1, it would give those with tank slosh issues a way to convert a current DS2 to the new in bucket setup or allow for a new install in their original module.



We already have prototypes built and installed in a few trucks. They do work. They would draw fuel from at least the same level as the factory pickup from inside the module bucket. This would eliminate all the fuel slosh problems associated with the DS2 or if you just wanted the confidence that you would never have a problem.



The DrawStraw would be positively located in the bucket. 1/2" draw tube would be standard. The system would allow for retrofit or new install. And, it would be simple, complete and hopefully, easy to install. This should make slosh issues a thing of the past.



With so many DS2s in the market, we are not sure if there is enough demand for this product. We are pulling all of our old test modules and we are going all the way back to 1st gen.



Please let me know what you think and we could most likely have units ready to ship VERY soon. I will also be happy to answer questions as this is a project I have wanted to complete for some time. We just need to know if there is a market. Cost is undetermined but should be economical.

I am interested.

The 1/2" Pipe I have been using works fine at 1/2 tank and over, but has the sloshing problem. It is extended down to about 1/8" from the bottom of the tank, but on any incline, you can see the pressure fluctuate. I didn't mind that because I kept it over 3/4 full most of the time via transfer from the in-bed auxiliary tank. But I recently removed the aux tank to add a camper. Now I find lt only has about 15 gallons of reliably accessible fuel without having a "sump". I have an extra (year 2000) fuel pickup assy that is the original style for that year (no in-tank lift pump upgrade) and plan to purchase and install the latest Draw Straw if it utilizes the oem sump. I hope others chime in as well. This is definitly a must do mod if someone is interested in having their electric pump last - JMO, tnx.

I just started noticing this problem this week in my truck. I guess with the winter temps I have always kept the tank over 1/2 and now that is has warmed up I let it go below. I am very interested in a fix that I can hook right up to the FASS line. The steel lines coming out of my factory module are all corroded and leak even with a rubber hose and a clamp. I will keep up on this thread as it's something I will buy if it fixes the 1/4 tank problem.

 

[MA2LA]

please do it. losing that capacity is driving me nuts. I have had the truck stumble many times and its not something I want to keep worrying about. I'm looking at a bigger tank but the cost is tough to justify.

 

[WOT]

I'd be interested. One option I was looking at was a toggle switch and a couple check valves to switch back to the stocker, in-tank pump when the FASS pickup was sucking air. Of course that doesn't push great fuel pressure but it is better then nothing.

Yours is easy. We already have a fix with the in tank pump. The DSV. Most of this will affect the non in tank pump guys and those that have installed a DSII at some point.

The corroded module fittings is very common.



This should be an easy fix for you. our plan is to make the install very simple and VERY reliable.

So I can retain a functioning factory pump AND move the FASS pickup to the one that is within the module/canister? You guys need to fix the "view larger image" on your website - still a very low-res picture and no bigger then the thumbnail. It also mentions using the factory return line to fill the canister, is that another connector or do tee into the return that is there?

Your factory pump gets removed. The module fitting simply replaces it and is positively located by the stock module's internals. There is no additional "Tee"ing of the lines. The return gets it's own dedicated return through the use of a simple Dorman fitting.



I know the pics are bad, they were taken on the fly and will be updated. I need to get into the shop and get some quality shots. I can tell you the system is complete and easy to install.

That's what I like to hear... . I can use the new pick-up from you and the other one as a return.

 

[WOT]

I guess I would lose my "backup" pump, but I suppose I could carry one if needed. Maybe as the weather gets nicer I might have to install this kit.

So I currently have two returns (factory one from CP3/injectors and the FASS return/purge). Are there 2 connectors on the replacement for returns?

Once you get some good pics that should help answer these, but until then I will just keep firing away

We use the original factory feed line Dorman connection as a return. So, no new holes are made for the return. This simply gives a full 1/2" draw tube along with in module bucket mounting.



I know it's not always clear as it types out. It may be best to call the shop about the particulars.

You could, but we will incorporate a return as well.

One more note, I have had many questions about what does a guy do with the DSII fitting if he chooses to remove it? Or better yet, what to do with the hole in the tank. We are way ahead of you here.



We have built a simple replacement plug for those looking to change the entire works. This is in prototyping and should be in production very soon.



Dave

 

[Fishin Guide]

Okay.



Got some feedback from a couple of testers. So far been positive, but we have made a very small design change. Most of the changes from here on out will be to simplify the design and to make it as easy to install as possible.



I have received some great input from those just looking, but the retrofit guys are driving the charge on this product line.

Another question for those in the market for the new products.



How important is bio fuel and veg oil compatibility?



Obviously, diesel fuel only tubing is easy. But we are finding some components do not like bio blends at all! We do have the proper products, but as they are extremely expensive to the diesel only stuff, we are considering making both a diesel only and a multi fuel kit.



The question really is, do we need both or should we only look at the multi fuel product? I would prefer to only make one item as we can assure the consumer that fuel related issues will not be a cause of failure. Or if a guy wants to run bio at some point he is covered. In the past, we have only done the multi fuel items. The reason is simple, trying to keep warranty and call backs at an absolute minimum. We want the products to work the first time every time.



What do you think?? I do not know the direct cost difference at this point as we are trying to establish expected needs/vs sales/vs turnover rates, ect, ect.



And as always, drop me a PM or give me a call if you need to talk in depth about your specific concerns. Although I would like to keep as much discussion as public as we can.

[PRohr]

I would take a #2 only kit but I totally understand why you want to make one kit and make it multi-fuel compatibale. As long as it isn't a HUGE price difference I wouldn't care but honestly if you haven't released pricing yet who would know.

 

[MA2LA]

I try to run bio asmuch as i can.

 

[TempletonD]

I personally feel the multi fuel set up would be the way to go. This way it would bennefit everyone. At times I run bio.

I am interested. I dont want to use any in take pump.
