bp-guy Posted July 26, 2013 Posted July 26, 2013 Already did that. Put one of my other ones back in the back of my truck with the WIF sensor "just in case". Quote
mush Posted July 26, 2013 Posted July 26, 2013 (edited) so what do they have for dodges then? fass systems? Edited July 26, 2013 by mush Quote
JoeDuner Posted July 26, 2013 Posted July 26, 2013 I think they are out of stock on the adapters. Mike was going to pick one up for me today, but they are on order. Quote
bp-guy Posted July 29, 2013 Posted July 29, 2013 I have a question- What would cause the fuel system to lose pressure after sitting a few hours. Truck would start then immediately turn off. I have to prime the system by pumping the primer then it runs fine. This just started and it never did this till I installed the new adapter. I am not here to bag on the product at all. It might be something totally unrelated. I don't see fuel leaking but I know the Duramax has had a few problems with that primer system and hairline cracks. Just looking for help. Quote
SAND~~SNAKE Posted July 29, 2013 Posted July 29, 2013 INSTALLTION error?? Some times the primer assembly leaks from the primer button , Replacement usually corrects the condition. Were you parked in the driveway at an incline? You have an 05 right? Quote

Since the filter adapter is billet and the housing is cast sometimes there is a difference in the sealing surface. A new filter housing will fix the issue and Underground will probably confirm this. Its the same as the Nictane adapter which has the same concern on some trucks. Quote
andydew Posted July 30, 2013 Posted July 30, 2013 When you installed and mentioned that it was hitting the block; Is there any chance you might've thread it on a little crooked and not gotten a proper seal? Quote
bp-guy Posted July 30, 2013 Posted July 30, 2013 Thats what I was thinking too (not properly seated). I will pull it off and re-install it. It was just baffeled on how air can get in but fuel doesn't leak out under pressure. It is on 04 LB7 Quote
andydew Posted July 30, 2013 Posted July 30, 2013 It could also possibly be the rubber O-ring On the filter Pop out of the groove... Maybe the primer I don't know... I believe the filter is before the pump on the suction side, So that would allow a tiny bit of air in without fuel blowing out, Due to the suction... Prime problems are a pain in the butt. I'm currently dealing with one on my Bigcat. Quote
dunefreak Posted July 30, 2013 Posted July 30, 2013 I was just baffeled on how air can get in but fuel doesn't leak out under pressure. It is on 04 LB7 It's because there is no pressure. It's a vacuum. The fuel system when running is normally pulling 3-5" of vacuum. There is no lift pump on these trucks. Quote

JoeDuner Posted August 25, 2013 Posted August 25, 2013 Anyone heard from these guys? I want to get this filter set-up, but it's impossible to get through to them. Quote
vegas style Posted August 25, 2013 Posted August 25, 2013 yea i had work done before my trip. oil change, cat filter, and a tune. they got me in last minute. i know they are slammed most of the time. maybe stop by they are close to you next to town square 1 Quote
JoeDuner Posted August 25, 2013 Posted August 25, 2013 (edited) Yeah, kinda figure I don't want to do business with someone that doesn't answer the phone. If I have to drive down there just to see if they have them in stock, I might as well order them online. Edited August 28, 2013 by JoeDuner Quote
nwtdiesel Posted August 27, 2013 Author Posted August 27, 2013 Nobody has called 20 times, we try to answer all the calls but it's impossible so when calls are missed we try to call back. If your local its best to stop in or email us sales@undergrounddiesels.com if we're going to get bashed for being a busy shop that's really lame. Joe we are out of stock anyway and can't help you so go ahead and order elsewhere. Plenty of people have copied our design so I'm sure you can find one. Thanks Quote
nwtdiesel Posted August 27, 2013 Author Posted August 27, 2013 Vegas Style thanks for the support. Yes we're busy and there is a reason for it. We try, can't please everyone. Thanks Quote
UDP_Mike Posted August 27, 2013 Posted August 27, 2013 Thanks for the post vegas style. We appreciate your business. You seen it with your own eyes how busy it gets here. Hope your liking the tuning. Let me know if you need anything. Quote
nwtdiesel Posted September 26, 2013 Author Posted September 26, 2013 No problem.... We figured it out! Our damn cordless phones are losing signal and not ringing. New phone set up on its way!!! Quote
JoeDuner Posted September 26, 2013 Posted September 26, 2013 Cool....did u happen to get the filters in stock yet ? Quote
nwtdiesel Posted October 3, 2013 Author Posted October 3, 2013 (edited) I have a few for the local guys, waiting on 200 adapters to come in. Trying to keep the adapters machined locally is out of the question so right now I am using a guy in Utah but now its looking like I might have to find another machine shop. Problem is I need someone with a machine hardly anyone has, the people who have them are backed up and I can not get the adapters in a timely fashion. If you can not get through email us sales@undergrounddiesels.com it goes right to mine and Mikes cell phones and we will respond very quick. If its between noon and 1 we don't answer since we are on lunch. Edited October 3, 2013 by nwtdiesel Quote
