while we are talking about the U hose. Has anyone just replaced it with the hose from Cohline?

I strongly urge customers to check any and all fuel hoses/lines every year - can't take more than 30 mins - any type and any combination - including Greg's uber fuel hoses. Just plain common sense.

We sell all of Greg's Fuel Hoses and depending on which year car prices differ. Email me at roger@928srus.com and I can quote you for your specific car.

I marked my clamps with red paint for just this purpose.

For those playing along at home, a bottle of el-cheapo red nail polish is perfect for marking things that have been torqued (factory QC stripes and spots) as well as using for telltales that something has moved. My 928 has these telltales in red and yellow from the factory. I added blue and green to the mix for various projects. The local 99-cents-only store often has the nail polish, Thrifty/Rite-Aid carries a more expensive version that's a couple dollars a bottle max. This stuff dissolves easily with brake cleaner between projects, so beware. If you really want a permanent mark, a roller-ball paint pen from an office supply or industrial hardware store might be better for you. You often don't have the same color options though.

Just to emphasize what Denny said so it doesn't get lost, using Oetiker clamps or Loctited and paint-marked screw clamps isn't 100% insurance in this case. Rob could have done a very nice job tightening these clamps and Loctiting them still to find the clamps loose a year or so later due to compression of the end of the hose while the clamp itself did not change dimensions. I'm not 100% happy with clamped ends on either of the pressurized fuel hoses, which would be the U section between the FPR and rear damper and the loop in the main fuel delivery line.

+1 on the Loctite Blue. Norma EFI clamps can be broken with an 8mm socket if they need to be removed again. I have the EFI kit on my fuel feed line on the passenger valve cover side. I checked mine since I didn't overtighten the clamps. I see no fuel weeping out, then again I used the 5/16" hose over these fittings, which was a bitcheroni to slip on.

I'm starting to think a good interval to check clamp tightness would be every oil change and inspect under the hood once a week.

Roger, I've heard numerous positive experiences with your lines on here as well as on the Pelican Parts forums. This is the first time I've heard of clamps 'loosening' themselves. Someone on here did your EFI kit 5 years ago and mentioned to me he still has not had any leaks while never touching the clamps.

I stopped selling the fuel hose kits because of issues such as this. I have the fuel hose kits on all my cars but I am also responsible enough to accept that I must visually and mechanically check them on a regular basis. I will sell the kit ONLY if the purchaser fully understand they accept all responsibility for fitting and using the hose kit. Providing the user is a responsible and mechanically adept person and considers changing the hoses every few years then there is no issue.
Far better to use the "Lifetime" fuel hoses, but that is certainly not a cheap option, but worth every cent in my book. I will as my pocket book allows be changing all my cars to Greg's hoses.

I think Roger was pretty reasonable and clear with his "caveat emptor" with the fuel kit.

I took the precaution of fitting two clamps at each joint- whether that hleps or not remains ot be seen and I tried to avoid overtightening them, pulling them enough so that when seated they rested lfush with the original hose diameter type of thing. There were enough clamps there to do that [more or less]. Hopefully I did not miss anything I should have changed out- I keep meaning to check on that.

I took the view that Roger's kit was infinitely better than not knowing whether my rock hard stock items were about to let go.

I would think if you check the tightness every couple of years tha tis about as good as it is going to get with Roger's kit.

I tightened mine before SITM, each took about a quarter turn. That's after 10k of driving.

Given how difficult it was to press the hoses on to the stock fittings I would be surprised if they leaked if the hose clamps did loosen over time. All choices carry risks. That is why I have insurance.
