Multiple Subaru Fitments Fuel Rail Plumbing Kits by Radium Engineering 

These plumbing kits are designed to compliment Radium Engineering Subaru EJ fuel rail installations. Both kits interface with the factory feed and return hard lines in the engine bay (near the LH strut tower) and provide all the underhood fuel plumbing. All necessary fittings and hoses are included, along with an adjustable high-flow fuel pressure regulator. Two kits are offered; one that feeds the fuel rails in series, and another that feeds the fuel rails in a parallel configuration. Both kits perform equally well. The end decision is based on personal preference. Scroll down for details on each kit.

This kit interfaces with the factory hard lines near the LH strut tower using SAE quick-connects or older hose barb connections. An adjustable Radium Direct Mount Regulator (DMR) and Radium 0-100psi fuel pressure gauge are included. The fuel pressure gauge can be installed at any of the 6AN junctions before the regulator using the included adapter. The 6AN swivel fuel rail fittings are low profile making them ideal for the tight spaces associated with the EJ motor. The variety of reuseable PushLok hose ends permit customizing (such as adding a flex-fuel sensor) making installation quick and painless. The included 6AN fuel hose can be cut with standard tools and assembled without special skills. Unlike standard low-quality rubber fuel hose that degrades with alternate fuels, the provided hose is resistant to all fuels including E85. The contents of the 20-0578 kit are shown in the photo below.

Because the hoses and fittings are consolidated, the parallel kit is a good option for cleaning up the engine bay. Each fuel rail is fed as shown in the photo above. The feed and return lines enter the Radium Multi-Port Regulator (MPR) from the rear and output through the front to the fuel rails.

very good book
Format: Paperback
I was 8 when the Union collapsed. I don’t remember much, but the years that followed were full of conspiracy theories and stories about who “razvalil Sovetskiy Soyuz.” This book tries to answer that question. You can sense from the book that the author is not happy with how everything ultimately evolved. The Soviet system was corrupt, inefficient, and ill, but probably there was a chance to cure it rather than kill it. However, I think the book is overall quite balanced and very informative and is a must read.

So very long….
Format: Paperback
Every time Yeltsin takes a nap? Paragraph. Bush mumbles something indecisive to Scowcroft? Boom—chapter! I felt like I was experiencing the fall of the Soviet Union in real, agonizing time. Look, it’s a fine book. If you’re going for a career in the foreign service, this is a good place to start. Otherwise, you can get a fine rendering of these events in much more concise form elsewhere.

P O W E R F U L .
Format: Paperback
The author summarized: "The ghost of the disappeared Soviet Union ... still haunts the imagination of contemporaries .... This amazing story teaches us not to trust in the seeming certainty of continuity and should help us prepare for sudden shocks in the future" (p. 439). An engrossing in-depth eloquent analyses concerning the events and individuals affecting the 1991 demise of the Soviet Union. Moreover, the unforeseen Chernobyl nuclear disaster on April 26, 1986, crystallized the horrors of a possible nuclear war. Thus, a new orientation to end the exorbitant arms race with the United States. Further, General Secretary Gorbachev promulgated new reforms, including, relaxing travel restrictions in 1989: "... [T]he shock that thousands of Soviet people experienced when they crossed Soviet borders and visited Western countries .... For first-time Soviet travelers to the West a visit to a supermarket produced the biggest effect. The contrast between half-empty, gloomy Soviet food stores and glittering Western palaces with an abundant selection of food was mind-boggling.... This experience changed Soviet travelers forever" (p. 82). At times, repetitive and somewhat confusing. For instance, U.S. President Bush needed Gorbachev's approval for his Iraq offense, which was initially described on Page 143, then inexplicably again, on Page 172. On another occasion, the author indicated that Yeltsin was influenced by Alexander Solzhenitsyn's brochure "How To Rebuild Russia," on Page 150, which is again repeated, on Page 173. Scrupulous editing needed. Notwithstanding such glitches, nonetheless, a fascinating detailed portrayal of the unexpected implosion of a superpower. Having read other books on the subject, if I had to select only ONE about the USSR collapse, I would choose this as the best.

Thought Provoking
Format: Kindle
I bought this book after I heard the author on a podcast. Growing up in the US we have been inundated with the story that the collapse of the Soviet Union was an inevitable triumph of liberal, Western values. I had my doubts. Even poorly run dictatorships can muddle along for years. What the author did was center Gorbachev in the story. He was the eye of the storm. It was the terrible combination of Gorbachev’s ambitious idealism and gross ineptitude that led to the dismantling of the Soviet Union. Unlike much of Marxist historical narratives which emphasize the forces of history; the author shows that it’s individuals who shape events and are shaped by them. A different person than Gorbachev could have turned the tide in a different direction and left us a different world than we have today. This is a history book that teaches lessons not just about the Soviet Union but about human history in general.

A compelling account of the fall of the USSR
Format: Kindle
Zubok describes blow by blow the series of decisions that sent the USSR towards disaster. Gorbachev, widely hated in Russia, comes across as principled but indecisive, ignorant of economics, and incapable of translating his worship of Lenin into coherent action. The book reads like a thriller despite the density of facts. Zubok is a pessimist, but his thesis is convincing.
