ok so i took off my UIM and TB today to inspect the leak, the PD had a slight crack on the lip and was yellowed and looked wet so we figure it's the culprit to my leaks.



i have an 89 t2, do i have to buy the whole new fuel rail to get a new pd?



anyone selling one or know a place with a good price?



kevin.

they sell just hte pulsation dampener at mazdatrix.com

Yes, 89+ the whole rail... It is all one unit on s5.

get rid of that ****

with what? a banjo bolt? Read that is not good for the injectors.

better than an engine fire...? hehe

Some have it setup that way with no ill effects. I would personally rather replace injectors x amount of years over an engine fire...

i just get a new damper, its cheaper than one injector

Marren Motorsports, http://www.injector.com, sells an aftermarket one at http://www.injector.com/fueldampners.php. It can be adapted to a stock rail fairly easily:

what needs to be done to adapt it, im already ordering 4 72lb (756cc) injectors from there hoping they fit my stock rails, so id like to order this at same time.

You can cut off your old PD and weld a 3/8" NPT male bung onto the end, or you could get an 87-88 TII primary rail, remove the PD, tap that end, and get an adapter to run the new PD.

what "adaptor" would i need if i went the "87-88TII primary rail with this dampener on it" way. im not clear on what the adapor would be for.

Good idea Ace, I think I might do this..

The PD in the picture is 3/8" NPT female. You will have to tap the rail with either a 1/4" NPT or 3/8" NPT tap. Then you'll need a male/male union to put the PD on the rail. Don't forget to use teflon tape.

Ok, you try it first. Then maybe I'll do it. https://www.nopistons.com/forums/pub...#>/biggrin.png
