I own a 4gen hatch std model. The car starves terribly around turns. I have to run a full tank of gas, it even starves at 3/4 tank full. I know there must be other 4 gen owners who have encountered the same problem. What did you do to correct the problem, such as modify the fuel inlet pipe in the tank? I used to own a 4gen si and it didn't starve as bad as the std model does now.

 

3/4 of a tank? Make sure the fuel pump is installed properly...

 

did std's come with smaller tanks? i know HF tanks are smaller. its typical EF cars will starve at even half full.

you can make a surge tank. http://toyotaperformance.com/surge_tank.htm

 

The car has to stay legal for SM, I just don't want to run a full tank of gas though. The HF tank is small but its 11gallon tank compared to 12gallon for the ef. I'm really not sure that will correct or help out the problem. Out of curiousity a upgraded fuel pump won't do anything will it? I don't think so but I"m not sure exactly.

 

This probably won't help, but my old '91 STD hatch never had any starvation problems, I could run the thing almost down to nothing.

My '88 CRX Si however has terrible problems below 1/2 tank. I've just been Auto-xing on a full tank. I suck anyway so the extra gas doesn't make that big of a difference.

My guess was always that the pick-up tubes weren't in the tank properly, but I've never pulled them to verify.

 

Wow, that seems kind of strange that your 91 std didn't have any starving problems. I would "think" that nothing has changed with that particular part on the car between 88 and 91, but I could be wrong. This has to be a common problem, hopefully more will chime in.
This problem give me a reality check as one of the problems of trying to modify economy boxes into race cars when they weren't designed to.

 

Have you checked to see the fuel pump inlet sock is still on the pump (if the car has one that is). I thought I had blown up my motor when I had a JRSC and the car was stumbling horribly with 1/2 tank of gas. Turned out I put in my high-flow pump and didn't zip-tie the filter sock that traps gas for the pump to pick up continuously, it fell off, and bam, instant fuel starvation during anything but steady, straight driving.
