Fueling problems at the pump

[khoov54]

Hello all,

My 98 Boxster has recently developed a problem with fueling at the gas station. While pumping gas I get a back pressure that stops the nozzle. I can only fill the tank by very slowly metering the gas flow. Is there a vent that is blocked?

Things I have tried:

checked fuse E6 and it's ok

taped the phone connector under the console

tried different gas stations

All suggestion are appreciated.

Regards,

Khoov

Unfortunately, sounds like your issue is the one in the tank. What happens is the flexible tubes of the fuel sending unit move and block the flapper valve from the filler neck. If you're a contributing member here at renntech.org (which is a good idea BTW ;)), check out TSB 3/99 2015

The fix per the TSB is:

"Affix the two flexible hoses in the fuel tank exactly as shown in Figure 1, using two tiestraps."

It involves pulling the fuel sending unit from the tank.

First thing I would check is the fuses. There is a fuse, E6, which if blown, will cause the filler valve to stay closed. The result is the car will not fill.

Go through and check all the fuses. I believe the fuse in question is labeled in the USA portion of the fuse list as a mobile phone or accessory fuse. I think it's a 7.5A fuse.

Good luck and welcome to RennTech!

i'm noticing something similar... any pump with that vent sleeve on it, i can only fill up 2/3-3/4 of a tank... but if i get the old school ones with just the nozzle and no vent collar, i can fill up to the top...

is this the same issue?

Sounds like a different problem to me. When fuse E6 is blown, you can't get any gas into the car, at least not quickly. It will just overflow. If you're not getting a full tank it sounds like something else is going on.
