I did test this afterwards to make sure my fuel pressure issue was corrected. The pump does, in fact, retain fuel pressure when it's not running now. I hooked up my fuel pressure gauge at the rail fitting and turned the igition on, watched the fuel pressure come, then once the pump ended its prime cycle and shut off, pressure stayed, instead of immediately bleeding off like it was with the walbro and its rigged venturi setup.

That bleeding off of fuel pressure is not harmful in any way except that it makes starts a little less natural and effortless. This is a bigger problem for me than most people because I wait until after the prime cycle to start the engine so my electronic boost gauge can calibrate itsself. If you have a walbro and start the car while its still in its prime cycle, which is what most people naturally do rather than wait, it's not really too noticable.

Thanks for the extra photos and advice about the corrugated hose. Do all walbros do this? Is that why you switched to the racetronix pump?

bouth pictures of the bumps still don't look the same as i had in my 96 :S....did they all have diferent bumps??
