Engine/Transmission (1998.5 - 2002) Need some info ASAP, please

[Detroitiron]

My lift pump went bad, so I replaced it with a Walbro 392, based on my research here. I have seen numerous references and recommendations to use a fuel pressure regulator, and searched until my fingers are ragged and I'm out of search terms, so any suggestions to "do a search here", please, save the idea for a different time. After searching online both here and on vendors' websites, 3-4 hrs a day for about 2 weeks and no results, I'm just not in the mood. I have found none that mention compatibility with diesel fuel, which is why I need a little help. I have a Westach FP gauge and it pegs @ 30 PSI. Also checked w/mechanical gauge, but scale only goes to 35 PSI, so I know there is way too much pressure in the system.



What I am in dire need of is mfrs. , model #'s, pricing if known, and likely vendors with good customer service and immediate or almost immediate availability.



My truck is a '01, 3500 DRW, 47RE.



thanks for any ideas or suggestions,



Dave#@$%!

If you put on a complete 392 kit it came with a regulater. You can take it apart and remove a couple of the washers to lower pressure. I just installed one a couple weeks ago, and mine was holding 19psi at idle. I removed one . 040 washer and the idle pressure is now 17psi. Randy

Call Eric at Vulcan.



He has the regulators in stock and they are fully compatible with your pump.

hindsight is always 20/20...

Randy, I wish I had bought the kit, then I'd have found the regulator in the box and installed it. I'm not sure if I had amnesia or just a brain fade, but thanks anyway. Dave

I checked Vulcan's website. Are you referring to the Sim Flo Bypass Regulator? The price is right (39. 95) and it looks simple enough.

I will call Eric in the AM.

 

[Fishin Guide]

I am unsure of the description. I held one in my hand last week and the design is ultra simple.



Eric machined a bypass for my fuel system that I will be trying out this week. If all goes well, I will have total control over pressures and still have the ability to run filtered fuel back to the tank.



Eric is always thinking!

yup, the by-pass regulator valve is what you need, it's not so much a fuel regulator as a pop-off valve that allows the extra fuel to be pumped back to the tank. you'll also need a fuel neck "T" that Eric has as well and some hose. traditional regulators just hold back fuel and the pump pushes against them, but the Walbros don't like that, that's the reason for the by-pass.

 

[Detroitiron]

thanks for the insight!

All the help you guys are giving is what makes me like this site so much. Thanks, Gary, I just learned something from you, and I really appreciate it.

Boy you nailed that. I have learned more in the last two month than I have in the last 2 years. I love this place.

Call Rich at Glacier Diesel Performance, the regulator is a bypass style and works great. I sit at 20psi idle and have never dropped below 14psi.

Just some ideas:



I run a RASP mechanical pump.



The RASP bypass with it is identical to a "JET-CAN" at Kinsler fuel injection.



You tell Kinsler what pressure you want and they bench flow test it to your flow rate. They are AN-6. You can also purchase spring sets and shim sets so you can set exactely what you want however you want it if you decide on some other pressure.



I like the bypass concept, very mechanical, the ONLY moving part is the valve. Failure is virtually non existent.

you and Fishin Guide are right!

I called Eric this AM. He filled me in on application and practical theory of the system he designed and I have one inbound via hurry-up-mail. One of you guys suggested GDP... BTowler, I think?... well, I checked their pricing and they are very proud of their stuff... 'nuff said about that...



Eric walked me through what I needed and even suggested the right relay I needed to use, as the Walbro has a higher amperage draw than the stock Carter... so I also ordered the pigtail and peripheral hardware for that. All in all, a very satisfactory solution to my problems. Thanks to all for the advice, suggestions, insight, and moral support.

ps... The thing at VA Tech... my daughter and her husband both graduated from there in the '90's, she lived in West AJ (Ambler Johnston hall), where the initial shooting started. . so a good thought for the victims and survivors would not be inappropriate from all of us.



thanks, Dave

Bob,



mine is built with a 12 valve overflow valve doing the pressure bleed duty and a simple barbed banjo into -6 and into my main return line to the tank. This is between the fuel filter and VP. So the fuel is constantly being filtered and does not slow enough to pickup much ambient temp on the way to the VP.

When I got mine Glacier's prices were very competitive.

I don't doubt that at all. Sincere thanks for the suggestion. It was one of the options the members here offered me, and that was what I asked for. You guys, all of you, are the kind of people I like to be associated with.



cheers,

glad we could help a fellow gear head.

 

[Detroitiron]

I just followed your advice....

I fixed it until it was broke... LOL...

Now if I could only find out where the 'turtle express' is, and maybe get my parts... I could finish what I started. I will post the results when that happens.
