TR6 PI Fuel Lines

Hello,

The attached image is of my filter/fuel pump arrangement that has been in place, I’m almost certain, since 2008ish when the car was with a PO. I’m concerned the lines are not ethanol proof but I have no way of knowing. Given that all but the filter to pump lines have no markings on them can I ask the collective for guidance as to what I should look for to ensure I get ethanol proof replacements. Presumably having copper to tubing without clips is also not the best thing? Is the braided line from pump to PRV likely to be Ethanol use approved? What donthe markings on the filter to pump link imply? And, finally, if I have to drain the tank is it simply a matter of cutting the pipe and let the fuel drain safely (with other sensible precautions of course).

Pre-2008 rubber parts are certainly not ethanol resistant.    Many suppliers now sell R9 spec hose for this purpose.

For 100psi a rubber hose  to copper pipe connection without a circlip does seem foolhardy.     Even better, a slight flare to the pipe end, easily done wiht a brake pipe flare tool.

Draining the tank?  Cut, or detach the hose beneath, and you have a flood of fuel just where you don't want it and it rather hazardous.     Make up an extension hose to fit after the pump, so that your receiver can be stably secured on the floor, and use the pump to drain the tank dry.      Then cut/detach the hose under the tank, with plenty of paper/floor cloths to catch the spillage.

And yet pre-1980 OEM rubber fuel hose seems to be more ethanol-resistant (and unleaded compatible) than some of the so-called R9 crap on the bay of evil... Choose your hose carefully.
