Are the fuel injector elbows that are available from the usual suppliers ethanol rated?
These elbows have the same NBR/CR (Nitrile Butadiene Rubber lined) & (Chloroprene Rubber outer) as my Cohline 2134 fuel line that failed at my tank connection.  I'm replacing all Cohline 2134 fuel lines with Cohline 2240 (FPM lined). 2240 has a 60 mm minimum bend radius so I can't make my own elbows from 2240. Are there any other elbows on the market? https://cohpro.com/cohline-fuel-hose/  |

No.
Use fuel line with an SAE 30r9 rating for ethanol. Go to your FLAPS and ask to cut some off the spool that they almost certainly have in the back. If they let you cut from the bottom of the spool they will have more then enough natural bend for the application without kinking. These days I refuse to use ANY fuel line that does not have the proper SAE rating printed on the hose. Also, use proper fuel injection clamps - not the cheap-o worm gear clamps. Zach |

Zach The plan is to use Cohline because Gates Barricade MPI 225psi Fuel Hose is fractional size and very stiff. I'm still running D-Jet on a 2.0L, fuel pump and filter moved to steering rack. What fuel line do you use? |

I'm still running D-Jet on a 2.0L, fuel pump and filter moved to steering rack. What fuel line do you use? I am using SAE 30r9 fuel hose. The SAE rating is important because you KNOW what its rated for chemically and for pressure. Its a relatively soft hose and I have had no issues with leaks on any of my aircooled german cars. I'm in the process of buying a Mk1 Rabbit pickup, and I intend to use the same fuel line on it. My FLAPS usually has a huge spool of the stuff in the back. My current engine does not use the stock fuel runners, but my 2056 did. I did not use special elbows, I just used small cuts to attach the runners to the injectors. Never had an issue with kinking, but you do have to be a little mindful when dropping or installing the engine. Use the good hose clamps - not the cut worm gear clamps. Real fuel injection clamps make all the difference. Zach |
