WHAT FUEL LINE

[NickOcean]

What replacement fuel lines should i be using, i see most people are say 12 mm - im assuming this is outer diameter. Though the ones i have removed have 7x13 >nbr/cr< e4219GA 177-96 printed on them at the rear of the car. At the front the 2 lines into the plenum one has WP 12 bar 5/16 13062, the other one i need to check, but they appear to be different as well. These lines are original to the car ex factory i think as i bought the car in 98 and it only has 11k on it now!.

Then I go on the internet and Iam confronted with a whole host of different hoses, im very wary of cheap knock offs, and wary of ethanol fuel resistance. Any guidance as to where to go and what to buy would be great.

i know nothing about fuel hoses! Anyone know what they are talking about who can help?

You need 8 mm ID for most of it and then some 12 mm ID for the rear tank to crossover pipe and crossover pipe to pump.
I would buy this personally in both sizes.

Good recommendation. Avoid braided. I had braided rubber hose on my Range Rover V8 and the inner rubber had perished but the hose looked great from the outside. Was doing some tuning in the engine bay, engine running and noticed the air looked misty. On closer inspection it was fuel vapour being sprayed around the engine bay through cracks in the hose that were invisible beneath the braiding!

Used this couple of years ago. From Demon Tweeks. Bit pricey but a least you know it's not fake from the far East. . With the mocal I bought 4 metres. Had to buy a metre of Cohline 2240 but you only need about 8 inches (tank to pump) so you'll have enough for the next 30 years.

Many thanks gentleman, especially the link. Lines ordered, stainless steel fuel line clips ordered, Bosch fuel pump ordered (that was expensive!). Mann fuel filter ordered. Next Sunday we will fit that lot. First part of the reanimation of the dusty TVR will be done. Really appreciate the help!

A customer of mine nearly lost a Jaguar XK150 due to this very thing looks good on the outside but crap rubber hose inside and the known Jag specialist wouldn't refund him (his problem not mine) I ended up replacing the lot with Cohline hose like recommended above because I had it in stock and its well over spec for 6 psi fuel pressure
