I see fuel hose listed in the parts. What is that for?

The two short fuel hoses on the fuel rail.

Just to replace them? Or do they need to be lengthened?

Its just a good times to replace these while you're in there. They are hard to access otherwise.

And do not use standard fuel line for these... You must use the high pressure type fuel injection hose.

Completed the task yesterday.

The only high-temp hose they had was red, but it looks decent. Ill post a pic later (on iPhone now).

I ended up using the stock hose off of the valve cover gasket and mating it to a piece of 5/8" hose with a stock coupler from the "mess." The 5/8" hose is he perfect size for connecting to the throttle body. Also, 1/2" is indeed the perfect size for the ICV to intake boot, but it takes a little muscle and lube to get it on the ICV.

The 5/8" is indeed a little to big for the coolant outlet on the head, but I was able to shim it with a piece of thin rubber tubing, and secure it with a hose clamp. It's not going anywhere.

I also replaced my injectors and the two rubber fuel lines.

After the new injectors and new gaskets, the car absolutley purrs now. I have a video that I'll try an post up too.

Hey Ken is that red silicone hose? Or a garden hose?

KenC · « **Reply #173 on:** November 01, 2009, 03:17:46 PM »

It's high temp heater hose. The red is a thermal protective layer on the hose.

Ok. Looks good. Thanks.

do you mind sharing where you purchased on your parts? i've having trouble collecting the 5/8" coolant hose and the high temp hose. i went to advacne and all they had was the fuel hose.

Oh. By the way I removed a lot of the underside hose as well. Cleaned it up really.

Sorry to bring this up again, but I'm going to redo the mess under the intake because the coolant pipe is leaking. This time around I'm going to plug both the block and the coolant pipe instead of using heater hose to connect them. I have read through this thread numerous times and was wondering what people are using to plug these ports? I've seen plastic caps and heard of people using bolts, but didn't know which way to go with this. Thanks in advance.

^I used silicon rubber caps from the Help! section of a FLAPS. Everyone has them. Only problem with this route is you might have to replace them once every couple of years because they will break down. I had one leak on me after about 12 months. @ $2.50 I'll deal with it.

Jorgeconrico · « **Reply #179 on:** November 09, 2009, 09:11:16 AM »

Did you use any type of silicone sealant along with hose clamps to make sure it was seated and sealed properly?
