Some of my blog readers might remember that bringing the shark home from transmission rebuild
was a bit of an adventure, to say the least.
Since then we were able to have some nice day trips (a bachelor party at Spa Francorchamps for example) but the problem of a blowing fuel pump fuse would re-occur every now and then and, as we all know- simply because there isn’t a good moment, always at the wrong moment. It’s a given fact that driving a Porsche is a reason to smile but if you’re driving a full day with an ear to ear grin caused by a deceased fuel level gasket in the boot and an amount of fuel sniffig that would even take Keith Richards down, you know you’ve got problem to deal with. After raising the shark up for the umpteenth time I have to drain about 50L’s of fuel, I guess there’s no need to mention this gets the Keith Richards routine going again.
Despite the fuel sniffing, my sight is still intact and the fuel pump seems fine to me but then again, what can visibly be wrong with a grey cylinder? This grey cylinder can run hot when any of the two filters is gummed up so next up is a visual inspection of the in-tank filter. If I had done some proper research on this subject I would have known better but since I didn’t, I’m making an attempt at unscrewing the in-tank filter. This mistake almost makes me go fuel sniffing again, the fuel filter does come out but it brings along a close friend: the metal collar.
Somehow it does makes sense: The 928 is one of Porsche’s intelligent designs but combining a metal collar with an aluminum filter and screwing this combo in a plastic tank? This has got to be a Monday morning design, invented after a weekend of heavy drinking or even worse, a weekend of fuel sniffing. I hope I can end the endless caress and bathe the romantic couple in Wally’s brew.
The day after sneaking up on the happy couple, I began checking the remaining parts of the fuel system. The remains of the deceased fuel level gasket were found at the bottom of the fuel bucket; the second fuel filter had seen better days. The date on it, 17/09/1985, probably says enough. What was that thing about overdue maintenance again?
Wally’s brew didn’t help in separating the “happy couple” so somebody suggested to boil the filter in vinegar. I’m giving it a go but I’m guessing this concoction was invented by fuel sniffing people. It wasn't helping at all but under the influence of fuel, I'm sure it was probably good fun.
I’ve had it with the romance, so I roll out some heavy artillery: drill, hammer, chisel, and a saw blade.
After a few hours I am victorious but also worried about the outcome of things. The old in-tank filter was a 36 x 1,5 thread and is NLA. The one that is available now is a 37 x 1,5 mm. The metal collar had the shape of an egg after my violent attack but its thread wasn't completely undamaged; the problem was that this egg I'd created had to get back in the tank. What started as a simple job is a now a matter of state interest and I’ll have to rely on all of my James Bond skills to succeed.
