I have a G20 Van and recently it just started to use lost of feul. I mean really heavy. 5 gallons for every 24 miles. No check engine light nothing. I did a tune up 8500 miles ago along with the o2 sensor and the TPS since the engine light was on back then.

HELP!

Check the pressure regulator and the return line to the tank, pull the vacuum hose off the regulator, any fuel in there? If so replace it, pinch the return line does pressure increase? Get a test guage, autozone rents them out, when your done they refund all your rental fees.
