Where can I get a reasonably priced pulsation damper for my 85 GSLSE? I smell fuel on cold startup and after shutdown, but no accumulation anywhere. I have heard Hondas use the same part. Is it true?

Don't want my baby to burn! Thanks for any input!

Remove the upper intake manifold and have a look. The pulsation dampener isn't known for being an issue on our cars like the 2G. My bet is that you have a leaking fuel injector O-ring or a pinhole in a pressue fuel line between the firewall and the fuel rail, or the rail and the return. Very simple to fix (only use high pressure hose rated and designed for fuel injection!) and recommended if you haven't changed these lately.

Reply back if you need help pulling the UIM, as it can be done in 10min or less once you've done it a few times. HTH,

 

and don't drive the car until you fix the leak. fire is bad, mmkay. it is ok to start it up and move it around.

 

I found a 2nd gen banjo bolt and fuel rail (?) and deleted PD completely. Ive read that its harder on the injectors but I havent had any issues since I did this ~ 8 years ago.

 

-SE injectors aren't as easy to find nowadays as they were 8 years ago. I'd suggest leaving the Pulsation Dampener on the end of the fuel rail, because it's designed in stereo - there's another one just like it on the fuel pump, and together they work to damp out the 'water hammer' effect of the pump running. With only one in place, you're down to 1/2 the dampening capability that Mazda - in their infinite wisdom - decided it was worth spending an extra $5 times 100,000 vehicles to make sure it all works correctly.

You can do otherwise, of course - and I've even heard of people 'dead-heading' their fuel system with NO return to the tank. I can't imagine that's any good for your fuel pump, either. Point being - getting the right part on there should be more about doing-it-right, than doing-it-fast.

 

I've never heard of return-less fuel system on an injected car, that'd be too much pressure built up.

The banjo bolt replacement has been brought up frequently in the 2nd gen section, search there too for more pro/cons.
