Hello Mike, this is the old DIN from the 80s till 90s like you can read on your hose. E3 instead of B stands for the biodiesel resistant FPM/ECO hose. And what's good for biodiesel is perfect for all kinds of ethanol blended fuel. Most dealer still say, the old NBR/CR hoses are o.k. for up to E10, but with all the crap in our modern fuel it's working 'on a knife's edge '. Wurth for example doesn't allow them any more for fuel systems and strictly recommends FPM/ECO-hoses. Best Regards Martin
Ok well it's what I have and they are new. And it has to be better than the original. And they look good too except for the smaller od. But thanx for your knowledge and info
