Yep - pulled mine and mine was 180 the other way... and squished. BUT that's the only way the aftermarket pump would allow it to go without modifying the bottom retaining plate that supports the sock and pump - which means my pump was not designed for the miata. Time for a new pump I guess

i got my walboro form a dsm, and fits just like yours. no problems. I did however have a problem like yours about 2 years ago. i was thinking fuel starvation as well, but i could add fuel and it would still do it. while corner working a pca de/tt one day, i was describing the issue to an older guy that ran a shop in town. He suggested that i first try a new gas cap. He said he had cars in for repair that had bad gas caps and wouldn't keep the tank pressurised. my gas cap was the original on a '95 with almost 200k so i figured it was cheap and easy to try first. ordered one from mazda dealer, to make sure i got a good quality cap, can't remember how much it was but i think it was under $10. well, that took care of it because i haven't had a problem since. give it a shot.

The internal sock and such are important enough that if I ever need a huge boatload of fuel, it will be an in-tank Walbro/DW300 feeding an external Bosch 044. I don't ever anticipate needing more fuel than what a DW300 can provide, though.

Seems MAperformance is the main dealer for the DW300 - time to carry stock Sav, or is there no profit in them? Anyway - the DW has applications for both models of the NA body which I thought was strange - in my limited knowledge base, is there a difference in fuel tanks between the two?

My experience agrees with Savington's statement. I had a fuel starvation issue that would pop up on the track in the corners when I was at about 1/3 a tank. Long story short the previous owner did a less than stellar job retrofitting a fuel pump. I replaced it with a Walbro with the proper pick up filter (the main difference) and viola, no fuel starving problems anymore, even when the fuel gauge reads empty.

Once we get our IQ3 and capacitive sender set up dialed on Crusher, I'll drop you a line.
We're using something like this with a bendable shaft. Scale it however you like in the IQ3. We tried a digital gauge with the stock sender and have struggled to get meaningful readings.

What I have learned is the fuel sock needs to be exactly like OEM and exactly in the OEM orientation and position or possibly just 1/4" lower for glorious fuel pickup to occur.
Installed a Detchwerks pump with Walbro mounting hardware and all problems went away. I have put more than 10gallons in without a fuel starve issue.
