I broke the EXACT SAME PART while installing my BHR fuel pump. Note to self (and others): Tighten pump first, THEN clip on the fuel line.

If you can find a broken FP from anywhere you can just swap the top plastic piece and you're good to go. That's what I did.

I would however recommend the BHR fuel pump upgrade. No more fuel cut on high g-force left turns! Actually the day I swapped it I could barely drive straight at low RPM, the FP kept shutting off every a few miles. That thing is almost as weak as our coils...

How did they manage to step through the steel access plate that protects the pump?
Why were they "stepping" on your seat and did they weigh 700 pounds?

Me either! Damn

Well I have cured my 1st/2nd gear belt slippage. Dang engine spins up so fast i was having a time with this before. The rest of the gears were ok.
What I did was to buy a belt that was 1/2 inch longer. I then took the idler pulley adjustment bolt out of the slot, tighened the belt tension with a wooden pry bar (never use metal) and once tension set I tighen the idler pulley. I then used the head of the adjustment bolt to back up on the slot so the idler pulley could not back out any. You have to be careful of the pulley alinghment.get that right or the belt will squel like a stuck pig. This will get you more blower pulley wrappage from the belt./
Now just using the belt tension rule of twisting it 90 degrees with your hand, i am not getting ANY belt slip, even in 1st gear

I already (as I have a race next week) order a new part at onlinemazdaparts.com !
But I already have a 255lph fuel pump (not walbro) & the mazda fuel tool

Yah - but how did his knee go through a 14ga steel plate? (And 2" of dense foam and leather.)

To the extent that is relieves any potential air pressure in the engine bay it is a good idea if executed properly and many have seen benefits from it.

Racecars like to have negative pressure under the car.

enclosed hood /engine bays can actually cause lift at high speeds.

What ever happened to the cooling mod rotr8 was trying out in the lower part of his front bumper? I do not recall if it was a Pettit design though.

It's too early in the summer but it seems to be working (installed this winter). I need a few more trial hot days with temps over 105 before I comment further. Was pleasantly surprised on a recent trip with air temps at 110 and speeds in excess of the speed limit, my temp never got above 203 degrees F. But will it work in stop and go traffic on a 117+ degree day? That will be the real test.

with too much pressure in the engine bay has resulted in a 1-2 inch lift on the front at 100+ mph. This was not an RX8--it was a domestic car.
The 8 has pretty good engine bay airflow on the track---its low speed flow i am trying to address.
