I would be fairly certain in Boston there will be industrial bolts suppliers. In Calgary we have 3? hardware suppliers specializing on bolts, nut, screws and the likes. Metric stuff can sometimes be more of a challenge, possibly in the US where SAE is predominant thread sizing. A 2 second google cam...

On mine it was easy, they just had to look at my epoxied fuel pump top (I didn’t want fuel blowing up my car) and smell the gas from the seat bottom. All they really need is a “yup, top of fuel pump is cracked” so they can work a ticket with Volvo USA. I don’t know why dealers sometimes make it mor...

You can empty some/most? fuel tanks using a small tube into the fuel filler tube. The tube must be about 3/8 inch or smaller to get it worked past the anti syphon flapper in the tube. If it gets stuck, twist, push and pull to work it loose. A hard nylon tube has worked best for me. Soft rubber will ...

I use this cheap siphon rig, works well on P2 cars (S60, V70, XC70 01-07). Just did an S60 fuel pump with it this weekend. The nylon tubing I just had laying around, not sure the dimensions, but 7/16 OD x 1/4 ID is close. With the tubing cut to an angle on the input end, the point slips right past t...

Yes, can siphon it back in but you'll need to put the gas container up high, like on top of the car. That's what I did. I just used an old plastic gas can, it wouldn't be great for long term storage but for the day (or a day or two) it's no problem at all. Also, would make much more sense to just pu...

Finally! After 6 months of prefect behavior the car finally failed to start yesterday, with very strong cranking, reproducing the issue that initiated this thread. In my driveway with the tank half full. Removed the rear seat and fuel pump electrical plug to discover the pump is receiving a ~1-seco...

Nicely done, sounds like you work carefully. Hope it fixes it!

A power supply issue? Maybe a loose ECM?

check battery clamps.

Check relays in the CEM, big ones controls power to BCM, ECM, TCM, etc. CEM can be faulty, too. Check for water leaks under cowl, the CEM access panel is prone to leak.
