5/16 Fuel Hose for 1.7 D-Jet, Source for SAE 30R9 (FI fuel hose) ?? Options

[913B]

So I ask the FLAPS parts person for fuel line hose and he gives me this. Then I check online with the SAE J30R7 rating stamped on the hose. It says operating PSI is 50 and burst psi is 250.

Is it safe ? Perhaps some members with deeper knowledge can confirm??
If so whats with the warning of dont use on FI cars ? Maybe modern FI cars and not the ones like 39 years ago maybe.

Thank you all !!

Correct lines are 7mm ID x 3mm wall, with means the OD is 13mm. I've seen this sold as both 7x3 and as 7x13, and it ain't cheap. That 5/16" fuel line is almost 8mm in ID. You may get it to seal with a tight clamp, but it'll too easily leak when it thermal cycles and starts to loose its stretch. Even Goodyear says it isn't for fuel injection.

I've heard of some people using BMW 7.5mm lines, but I'd stick with the right stuff. Too many 914's have burned up because of engine fires, and even the factory did a recall to replace the original cloth-braided 7x12 lines with these.

I also wouldn't go with 50 psi working pressure. That doesn't even give you a 2x safety margin....

While you're at it, be sure and get the correct clamps. Standard gear style clamps can cut through the outer skin of the hose, and lead to leaks later, or worse.
