| Other Fuel System Pump problems |
Bad fuel vapor smell in cabin, no check eng light on. Checked eng light at auto zone anyway, code said vapor valve going to canister/dump after warm up. Hyundai by phone said canister needed replaced($400+). I live on disability ssi, too expensive. Took to small garage, after lifting, bottom of gas tank was wet with gas(by the exhaust). One guy went to acess point for fuel tank for replacing fuel pump. A 6 inch rubber hose connecting the line out of the fuel tank connecting to metal rail fuel line bent at over 90 degrees, had a hole at the weakest point, in the inside bend. I am not the first owner, but damn, could only drive it after midnight in hot summer. Code explained car after warm up opens this valve to dump vapor build up in canister. Sounds right, code and everything, after I finally had them check for codes without check engine light not coming on. Such a cheap cost of a rubber hose could have easily been a braded flexable metal connection. Damn, I'm lucky. I gave Hyundai dealership repair guy over the phone the engine code.
