Aftermarket fuel rail installation help

Hi,

 

I ditched the old fuel rail and bought a new after market one. It's very common among early Z cars to have this exact update if you do EFI.

It's a Pallnet fuel rail with Supra 7MGE injectors.

 

However when I installed mine it feels a bit flimsy:

 

1.The only thing holding the injectors is the fuel rail pressing on the injectors into the manifold, does this look right?

(There is also the O ring inside the manifold but that is only a seal, not a fastener).

Stock injectors are bolted into the intake via fasteners and O-rings.

 

2. The brackets on the fuel rail allows for a little bit of movement. It's almost as it is intentional, the stock fuel rail was rock solid.

All fuel rails MUST be secured.......Somehow. There is 40 to 60 lbs of pressure going through the rails.

 

There are aftermarket units that sell the mounting brackets separately.  I have seen more than one car burn to the ground by not securing the aftermarket rails. Call the company you purchased your rail from have a chat with there tech.
