  • Tartarini regulator problems

    I have a 6.0L 2500 4X4 CNG suburban with an ECO Fuel conversion with FMS. This has dual Tartarini's. The water fittings on the regulator were leaky and I fixed this with a little rtv blue since I couldn't find anyone with replacements. I had leaks on the inlet o-rings to the regs. This appears to be the first stage of regulation as well. Once I replaced these viton o-rings and re-assembled the regulators I had no CNG leak but the regs no longer worked. The solenoid valves (tartarini calls it the safety system) operates properly, however no gas flows through the regulator. I am reluctant to replace the regs since they worked fine, other than the leak, prior to removing them. I suspect something is binding up in the first stage causing them not to work. Is this something that anyone here has experience with? Is there a rebuild kit for these? Perhaps a drop in replacement?

    I also have a 2000 Silverado 5.3L (single reg) that is the same equipment that also has a coolant leak due to the bad water fittings that I am reluctant to fix based on what has happened to my Suburban. Thanks for any help.

      Once you get the fittings straightened out I can get you a rebuild kit for $150 per reg. Or Mogas and larenzo have replacement regs that will work in place of the Tartarinis, about $650 each. Regardless of what you go with rebuild kit or new reg, you will have to go through the setup procedure when the work is complete

        RP/76-95 is what is printed on the regulators (see picture). I put everything back in the same way it came apart, one regulator at a time, so I would find this hard to believe but if you have a PDF I will look at it. Thanks

          I have not heard of Mogas. I have been told that one Landi Renzo regulator will replace the two tartarinis? I may be interested in the rebuild kits from you. Do these include the water fittings? Please either post or PM me on how to contact you to order & pay. Thanks

            If you are in Arizona as your name may indicate and if you get stuck drop it by and we can do everything for you and just get you the rebuild kit for it.

                Bobby, Thanks for the pdf file! I am going to pull out the first stage and see if I have 52, 59, & 58 in the right order. I post again once I have.

                  I wanted to thank bobbylink for the pdf's. I did have an opportunity to pull the regualtors and re-ordered the parts in the primary regulation stage. Sadly this resulted in a complete failure of the regulators once I re-installed them and eased on the gas supply The primary stage overpressured the second and third stages. I know that I need a re-build now, I just hope that the kits have all of the diaphrams for all of the stages. Just wanted to post the update.

                    Can anyone tell me where I can find a rebuilt kit for the same regulator shown above?

                    Thank you.

                        I'm also looking for a rebuild kit for a Tartarini regulator... anyone with contacts out there? Thanks!

                        My specific problem with the otherwise operational regulator is that there's a leak from the regulator into the coolant system (verified... it would actually pressurize the coolant system and natural gas could be smelled coming from the coolant recover tank)

                          I have even seen one of these things but if anything like a impco it sounds like a casting problem as there is no reason for the gas and coolant to be on oppesite sides of anything except the housing

                            Re: Tartarini regulator problems

                            I have a Tartarini RP/76-95 regulator. When cold weather starts, it will start leaking coolant. BAD!! A gallon every 4-5 days. In the summer I do not have this problem. I cannot go through another winter adding coolant. It only does this in cold weather. Does anyone have any suggestions?!? Should I replace the regulator all together or is there a rebuild kit available?

                              Tartarini made rebuild kits way back when but no longer, you may be able to find some new old stock somewhere, but good luck, they problem will creep up again anyways sooner or later. Instead replace it with a Mo-Gas or Larenzo reg. I replaced mine with the Lorenzo and seems to work better than the original Tart.
