Fuel injector hose replacement - clamps vs 'hats'

I'm in the midst of replacing the fuel injector hoses on all injectors on my GTV6. I ordered the nifty kit from Centerline that includes hoses, and both the stock 'hats' for each end, as well as standard hose clamps.

I just removed the first hose, from injector and rail, using the recommended soldering iron, etc. What a PIA!! Can someone give me a reason to use the 'hats' instead of the clamps? I don't care about the look - I'd prefer that it be more easily maintainable. Another 12 hose clamps amongst the hundreds on the top end of that engine would, for me, be barely noticeable.

Do the stock pieces somehow provide a more secure fit? Were they used just because it was easier to assemble at the factory? Curious!

thanks in advance!

I don't think clamps would make any future service easier - the hoses would still be held quite firmly on the hose barbs*.

*assuming the hoses are the correct replacement size. The fuel rail to injector hoses are a specific metric size. 7.5mm ID IIRC. 1/4" is too small and 5/16" is too large.

I use clamps and so do my friends who race GTV6's. Ideal brand clamps are smooth and do not dig into the hose.

Seems like without the hats, I could cut the full length of the hose - and remove it much more easily?

I believe the reasoning behind using the soldering iron instead of a knife is to avoid nicking the hose barbs which might lead to a leak.

The only time the hoses need to be R/R'ed is when their life is nearing an end. In other words, R/R'ing the hoses isn't done for any other routine work.

Yep - that's the kind I figured you meant - definitely what's needed for fuel lines. Summit Racing has them for $9 each - but I think Grainger has equivalents for less. Thanks!

Just went to garage and started removing hoses, thinking I'd have to order good hose clamps, and I find that the Centerline kit I ordered has those exact clamps. Thanks Centerline!
