replacing fuel lines

Postby sheriff464 » Sat 24.11.2018, 18:12

Are the feed and return fuel lines identical for both SE and S2? The return fuel line that I ordered from De Roure parts (Bell/Colville) is different from the one on the car(S2). That appears to be two small pipes running alongside the fuel feed pipe! The return fuel pipe I have received from De Roure is a single pipe with the same diameter as the fuel feed pipe. Can anyone give me more info please?

The parts book shows the two pipes to be the same diameter and it shows them for ALL M100 - Normally, if it was different for S2, they would have a notation like "VIN R 6001 (s2)" as a change point for a different variant.

Part Number A100L0130F for the FEED Pipe
Part Number B100L0112F for the return.

They match the lines used on the 1991 only FED car.
As always, maybe they ran out and substituted until more could be made.
Maybe someone made a custom line for some reason? Like a test to see if it made a difference? Lotus would leave the test in the car when it got sold...

Is your's an early VIN or a later VIN?

British Car Nut, thankyou for your rapid response! My De Roure pipes are as you quoted. Fuel feed (A100L0130F) and Fuel return (B100L0112F). My car is a late VIN (SCC100ZT1SHA26742). As you state, maybe at some point in it's life the return pipe has been cobbled! So, my mobile mechanic is booked to replace the lines next weekend. Cheers from Sheriff 464.
