Fuel Filtration Scares Resolved
As some of you guys remember me freaking out about poor filtration into the lift pump, I decided to remedy the situation. I know I'm being a bit paranoid, but what the hell.
Old Set up
Lots of crap at the bottom, makes me wonder what was making it through the approx 1/16" holes in the mesh.
The new system I've dubbed Phase 1
Not much gonna make it through the 2 micron filter normally used on big rigs
I put an inline filter without the filter before the new setup so I would be able to identify leaks quicker. That and I like seeing the fuel
Phase 2: I plan on adding a real fuel water separator to the system that will replace the secondary fuel filter
Phase 3: A fuel air separator that would replace the lift pimp and the OFV at the same time

That's a pretty filter. I like Baldwin. I'd like to see the bracket that holds that to the firewall.
You'd best go to an electric lift pump before that filter then. Even minor crud is going to overtax the OEM lift pump, which is not designed to suck well. Though I once measured 11" vacuum on mine, I wouldn't expect it to do that for very long!
And if you add a lift pump, what will filter the fuel to it? AHAHAHAHAHA! Chicken, meet egg.
Yes, I think you're nutz. I mean that in the nicest possible way.
I might scrap the OEM Secondary filter in favour of something like what you've installed, but not the primary, which is there only to keep boulders, bugs, and screws out of the lift pump. Not many lift pump failures on the SD.

Tell me about that diesel fuel turquoise COLOR. It looks like Winterized still here in June! That's the sort of stuff that contributed engine knocking in my engine until warm up.TooManyIdeas wrote:As some of you guys remember me freaking out about poor filtration into the lift pump, I decided to remedy the situation.

How about a fuel pressure gauge on your dash view?
Where's your air filter gauge? Don't want dirt clogging ya down.
Trick truckers have a pyrometer. Ya gonna get one SOON?
Does your DPC still shut off your engine if/when your engine oil pressure fails?
How about a starter/ammeter drawer?
How about a brake line pressure gauge?
WE got quick special about how to fix your under dash heat fan leaks.
Come on!

Philip, don't you know that turquoise is one of New Mexico's main exports . Actually I didn't know it wasn't supposed to be that color. But like I said I don't really have a chose in what comes out the pump. My truck doesn't knock during cold startup so my best guess is either laziness on the fuel supplier’s part or it has something to do with the elevation
However I got a buddy who is about to start making some home brew biodiesel. Other than the viton lines got any advice for a swap over?
As for the bracket I made it out of .080" 347 1/4 hard stainless.
I made it to utilize the factory holes. It may look flimsy but trust me it aint goin anywhere. The factory sheet metal screws however are a different story. But this setup is only till I go to Phase 2 and 3. The Air/Fuel separator has a built in pump meant to replace the factor lift pump.

I saw ... and chose "turquoise" color in you area. When I was semi driver, I can't recall a truck stop that didn't have Navajo turquoise stuff. All the south western places!TooManyIdeas wrote:Philip, don't you know that turquoise is one of New Mexico's main exports .

Al has LONG AGO vented about bio-diesel on several forums here. I say ... while you have a bunch of $$$ to waste then ... have fun. Learn a LOT(:shock: ). I've tried and learned ...

BlueSun Biodiesel (blended in Alamosa, CO) has a blue tint to it. I believe it to be a dye because no other biodiesel I have used has the same color.

I love biodiesel. I don't like WVO/SVO. That's the summary of my opinion.
Making biodiesel (transesterified oil) requires rigorous process control to yield consistent fuel quality. Inconsistent fuel quality leads to almost certain engine damage. I don't make my own BD, I buy it.
Our biodiesel is purchased, I think from Sequential Fuels in Seattle (a large BD plant is being built in Aberdeen, online in the next year I think), and our BD is golden in color. It's slightly but noticeably more viscous than D2, coming out of the nozzle and into my Maxima. As Philip has noted, it smells a bit like house paint
I love biodiesel. No sulfur (no acid rain). Mostly carbon neutral. Domestically produced (so far). Less smoke (in my rigs) than D2. Cleaner lube oil (at least that what it seems to me; I just changed the Maxima's oil at 4000 miles and it seems less ugly than previously; first full OCI on that engine with BD only as the fuel).

The stronger the biodiesel mix ... the stronger the stink of "house OIL paint" it is. That tells you peoples a clue about why rubber fuel lines need to be specific. I have found that pressure oil rubber lines for ATF (automatic transmission fluid) has worked ok on my SD22. But I do not use 99 biodiesel all the time. Matter of fact, the local stations only have B20 mix.asavage wrote:-snip- As Philip has noted, it smells a bit like house paint

At fuel stations having biodiesel, is there "Winterized" biodiesel were appropriate? Tell "TooManyIdeas" a little about cold and high elevation around ABQ, NM. (5,355'). It takes only 35 miles driving to Sandia Crest (10,678'). 25 miles flying crow.
Hmmm.... one SHOULD be smart about that "Altitude Compensation" on the injection pump.

There is no uniformly-applied policy.philip wrote:At fuel stations having biodiesel, is there "Winterized" biodiesel were appropriate?
Our distributor doesn't do anything to the fuel for winter. I don't know how they get it out of the tanker when they deliver in December. We have a small space heater in our storage trailer that keeps the fuel at about 50°F. I put out 2/4/8oz PE (polyethylene) bottles of Power Service Biodiesel Anti-Gel treatment in the trailer as a self-serve sort of thing, they sold well but I didn't get any feedback as to how well it actually worked.

Are you suggesting that pure biodiesel 99% turns from liquid to yogurt well above ice (32°F) ? What about my big $$ micron trick filter(s)? Do I heat my truck or do I mix with D2 diesel? Maybe mix with exotic chemicals?

If you have any truck junk yards near you check out the mid/late '80's Isuzu cabovers with the 4BD1T engine. They use the same lift pump as our trucks (and a very similar IP) and have a neat two stage filter head and water separator that is easy to transplant. I would imagine that the Nissan/UD's were much the same but I have never worked on one.......

Phillip what are you talking about. You were the one who commented about the winterized fuel. I made a guess on why it was that color and mentioned a friend was making bio diesel. What did you think I ment? I'm pretty confused?
