Intake Manifold Swap Questions

[sandman0023]

I'm going to swap out my stock manifold with a TrickFlow Street Manifold this weekend and have a few questions. The manifold came with a gasket connecting the upper to lower. I have a gasket set for the EGR spacer and TB, what other gaskets do I need? Is there a kit I can buy?
How do I release the pressure out of the fuel lines? I'm swapping out the rails as well and don't know how to release the pressure.
Is there anything else I need to know or do before I start?

Thanks in advance.

To relieve the fuel pressure, the easiest way that i have heard is kick the inertia switch and run the engine. Also I think you will need the heads to intake gaskets.

intake

if ur using a stock throttle body u have to order a kit through trickflow and u can just unscrew ur gas cap to vent pressure and dont prime the motor befor u start taking apart and u need the gasket between ur heads and the intake

To release the fuel pressure...you can either let the car sit for a while and the pressure will eventually go down (mine does it overnight)...or you can take the cap off the schrader valve (behind alternator) and use a flathead screwdriver or something and open the valve like a bike/car tire...but use a towel or something so you don't get fuel everywhere...

You might aught to get some new O-rings at your local parts store for your injectors...and mark all the vacuum hoses with tape...

Here is what I did on my intake install: I put a couple dabs under the FEL-1250 gasket and positioned the gasket over the ports as perfect as possible and then allow those dabs under the gasket to dry...so it will not move as I lower the intake on...You can also screw some "headless" studs into the heads to help you properly align the lower intake as you lower it down...and then just unscrew them when the intake is down...

I put a nice thick bead of high temp silicone on the block ends and let it sit for about 10 minutes to "film" over and then set the lower intake on...you can use long studs installed into your heads to help you lower the intake down and then remove the studs after it is seated...

I slightly torqued the intake down after the "filming" and laying it down just to get a little "squish" on the silicone and let it sit overnight...

The next day I did the final torqueing procedure with the torque numbers (somepeople go by feel) and that was that...absolutely no leaks of any kind...

On mine I had to trim a little bit of the coolant passages on the gasket because it was protruding into the passageway...

Oh and clean the gasket/head/intake "mating" area real good and clean...

Good Luck

to get rid of all fuel pressure find ur inertia switch in the trunk behind the plastic interior covers (its red) then turn ur car on and pop the switch up with a small flat head screwdriver. The car should shut off in about 5 seconds and will have no little to no fuel in the rails.

you will also need fuel rail remover clip thingies, they sell them at pep boys and autozone. U wont be able to get the rails apart without them. They are only like 5 bucks tho.

Yeah you will need the a/c-fuel line disconnect tools...they are about $10 bucks for the set and they come in handy for the fuel rail, fuel lines, a/c lines that have those special fittings...

I didn't replace my fuel rails but I just swung the fuel rail out of the way while I did the install...you had to loosen a head bolt though on mine...because a "brace" that holds the fuel rail down so to say...

Thanks for all the help. What about gaskets? I have the gaskets for my TB and egr spacer as well as the ones for my valve covers and the one to connect the upper and lower. What other ones do I need?

intake to head gaskets

I used the Fel Pro 1250 intake gasket...they are around $20...

I would do a search (or make a seperate thread) and find out who is running your intake on stock heads and see what gasket they have...

Good Luck
