on the actual pump itself 50k was the mileage I was given from the place I bought it used from. the internals only about 150 miles if that

after cleaning up pump and reinstalling the car is feeling better but my idling ltft are fluctuating. sometimes around -10 sometimes -13.5. do these numbers sound off? under load I've been around +0.6

so going over my original pump parts that were left over from the local shop when they tore it apart to extract my corksport internals and I found that the used pump I bought to get a new screw nut (supposedly off a cx7) had autotech internals in it :eusa_doh: guess it doesn't really make a...

this definitely gives me peace of mind about driving it to and from work which I don't really have a choice on lol until tomorrow morning at least when I can pull the pump and try to clean as best as I can without pulling the internals out for the sake of avoiding another fuck up :shakehead:

how about my pressure dropping down to 270-300 on deceleration when fully letting off the throttle in gear? pardon my mechanical ignorance :( also my cold in tank pressure has seemed low now. around 48-54psi

no codes, but been checking for them pretty frequently. my relief valve test got up to 1800 before slowly dropping, I've seen it's supposed to be at 1850 before that happens. would you know if this is an issue with my rv?

I can see the thread title of probable solutions to my problems on MSF yet can't follow any links, the time I need it most :clap2:

I've been spending lots of both on this situation already unfortunately and time isnt on my side. I have Saturday off though, so I will pull the pump and clean it then, leaving the internals in place since I don't have a great vice. I drove the car about two miles home from work this evening...

would it be stupid to take this situation to Mazda to deal with? I would stock out and flash back to stock beforehand

I had a shop assemble how it currently is... and to be honest not sure if I trust myself after last time to even fuck with the pump especially without a solid vice

92octane and 5w30 Castrol gtx

so another update. fuel pressure is dropping like a MF while cruising. got all the way down to 57psi!! I took a log if anyone can check it out that might know what's going on. hit up corksport with a log as well. been doing relief valve tests and that looks to be fine. first noticed after doing...

hey guys, had a local German autoshop extract my internals from my pump. figured since it's a Hitachi pump they would be more familiar with the specificity of my problem. they literally had to cut the pump open in order to get my internals out! I'll put a picture up later of the mangled pump but...

im honestly thinking about just taking it in to a local auto shop to help break it loose and just install it with the screw from the used pump I bought.

here's a picture of its current state. cotton strands everywhere from cleaning bits of shaved metal from stripping the shit out of it. definitely need to get it disassembled to clean it out thoroughly :(

everything was lubed up nicely. I followed the corksport instructions to the T but will admit the vise was definitely not the best and the socket used could have been better. you are more than likely right as for the aluminum though, it is soft metal for sure

yeah I used a shitty deep 18mm from harbor freight that I had to compress the spring to reach the bottom. coupled with a shitty bench vise are most likely the reasons I stripped it. I would trust how tight I have it now and install it to see if it's alright but the metal shavings like you...

my new corksport internals are stuck in my pump! went to torque it down to finalize my install and it wouldn't go that far. removed it twice to make sure it was threaded correctly and threaded with ease but would not torque that far. now my bolt is stripped from trying to get it tight enough and...

.

it hasnt been replaced or serviced to my knowledge. how/where can I go about inspecting the part to see if it needs work or if i can move forward with mod? better to get a full inspection at that point?
