i know that the braided hose is what we are looking for with vintage cars. but i would rather use non-braded hose suitable for high pressure and high temperature and avoid the potential of fuel hose bursting.
on the e30 m3 SIG today, there was discussion about fuel hose.
one person asked - "I need some 8x13 fuel hose and the BMW stuff is really high priced. Does anyone have any experience with Rein hoses? They are less than half the price of the BMW brand. Alternatively, any experiences with a brand called Cohline?"
and it was mentioned - "do not *EVER* use the CRP or Rein (same company) branded fuel hose; frankly, its absolute shit. wholesale suppliers like Worldpac and IMC still sell it, even though many folks have complained about the sub-par quality. i replaced all the fuel hoses in my e28 m5 when the engine was out 5 years ago with the CRP 8x13 hose, and over the course of 2 years/4500 miles, they had all dry rotted and cracked. glad i caught it when i did;"
one of the higher quality fuel line suggested was Gates Barricade. It was also mentioned that Continental makes a lot of the fuel line for BMW - there are a couple of types - some 50psi, some 100psi ... the 100psi also goes to 275 degrees. the bottom line is you need to know what you are buying.
