can anything be done about the fuel line connection under the UIM?
When I installed this motor I removed all of the emissions and replaced all the remaining hoses. The hose clamp on the fuel line under the upper intake manifold wasn't as tight as the others and decided to start leaking last week after only 6 months of service.
So tonight I had to pull the UIM to fix it. When I did I of course ruined the gasket and 24 hour autozone doesn't have them. Now I can't race tomorrow.
All because some little eff'en Japanese guy with tiny hands put a sensitive hose in a high heat and high vibration location that is impossible to get to.
Sorry for the rant. But is there something I could buy or make that will put this connection in a slightly better location?

Don't use crappy worm gear clamps.
a) Use the stock clamps. They never loosen from vibration, or
b) Use t-bolt clamps with a nylon plastic locknut.
There's several things you can do to move this clamping location, but none are as simple and cost-effective as the above-mentioned solutions.
As for the gasket:
1) Use some RTV for the Race tomorrow.
2) in the future, coat your intake manifold gaskets with a thin layer of high-temp grease. You'll never scrape another mating surface, and your gaskets will always be 100% reusbale.

Use the oem 'Jesus' clips (no need to ask why they're called that). They provide enough compressing force to hold that bastard on there.
Use RTV. I've been working on cars for years and only until 5-or-so years ago, I didn't know about gasket making material... RTV is the way to go.

rtv fo sho.
And if i could add rep for someone saying "coat your manifold gaskets in high temp grease" i would.
Damn good idea.
Yeah, dont feel bad man, i'm in the same boat as you. I missing out on all the octoberfest track events. 1. because car is pissing gas and has electrical problems out the wigwam. 2. trans went out in the dd....well, it's not dead yet but close to it and the money i want to use for events and tires and booze has to go for the trans.
Use jesus clamps.

Personally I hate those spring clamps. Especially now that I'm a tech @ Acura. I usually throw those clamps away as soon as i take them off. I know they don't loosen, but they are such a pain to remove, especially from tight locations. I even bought a set of pliers made just for them. a big waste of money.
I was wondering if there was a banjo fitting that would move it out or have a longer fitting that could be bent to a better location.
I haven't tried the high temp grease. I did use a thin coat of RTV but it didn't help. a one inch long piece broke out of the gasket around a primary port. the rest of the gasket is perfect.

Personally I hate fuel leaks, or disassembling an intake manifold, tearing a gasket and missing a race all due to use of an inferior to stock hose clamp. 
But to each their own.
I use a pair of linesman pliers to take the clamps off, it couldn't be more simple. I can't understand what's not to like about them.

I've got a set of foot-long needle-nose that have a 90deg bend in them, about the first couple inches of the tip... Those suckers work pretty sell, for that.

I used aftermarket spring clamps and they lost tension and leaked. I now use mini T-bolts and they work great. Also, on the UIM, Rtv the bottom half of the gasket then put a thin coat of motor oil on the top half. Next time you need to swap injectors or whtever it will pop right off and you can reuse the gasket. No it doesnt leak.

But yes, if I had used just one, here, then I would not be in the situation now.
