Ever since I installed performance coilovers and struts, with performance rims and tires, I couldn't be happier with the handling! Unfortunately the car now starts to stall or cut off after heavy turning, esp. when the fuel is low. Obviously there is an issue with not enough fuel getting to the fuel pump. But to be on the safe side, I checked everything around the fuel system, i.e. replace the pump sock, fuel filter, hoses, check wiring, and improve grounding, which all made a difference i might add, but I still suffer the same problem. Okay, so this is what I plan to do, but I would like some feedback if anyone has done this before. I plan on installing a Anti-surge tank system, or Swirl Pot, in which the in tank fuel pump feeds into the mini-tank under pressure, then another higher pressure pump draws it out to the injectors. so it looks something like this: That should take care of my cornering fuel cut problem but I just wanted to see if anyone has tried this before. Thanks!
That just seems like a whole lot of work (and money).. wouldn't it be cheaper to just not let your tank get below 1/2 full? Also check your fuel pump... there is an 'insulator' installed in the assembly between the electric pump part and the piping of the unit. Over time this tends to leak, bleeding off pressure back into the tank. You should be able to remove it and replace it with a piece of high pressure fuel hose and a couple of clamps.. this may fix your problem.
Have you seen the thread in the how-to section about removing the accumulator from the fuel pump assembly? Here
Already did that chief! As far as time and money: Volvo 740 turbo inline fuel pump: $1 1L Propane canister: $3 4 fuel line fittings: $1 each extra hose: $5 having a friend custom weld the canister: free wiring and putting it all together: 2 hours max Knowing your ride will never die around turns: priceless! And as far as the 1/2 tank thing...I'm used to cars like Civics or Miatas that never had this problem. The fact of the matter is, the Escort fuel tank was never intended to be used with higher g's. I'm not willing to bend to the car's will, the car will bend to my will!
neat idea! i'd love to do something like that but i feel like it would fail tech at the drag strip. losing fuel pressure at full boost in the middle of a cloverleaf is no good :/
I dunno.. I've taken my '95 scort around some pretty tight turns.. to the point in which the tires were about to let go... with the tank almost down to fumes and never had this problem...
I just got done with an 18 hour endurance race and had fueling issues when turning right. We may try the fuel pump mod listed here, but a surge tank would be the better way to go.
Scared This happened to me for the first time.....kinda freaked me out as my first thought was "Busted a timing belt!!". One of those 25 mph right hand cloverleafs that was 35 mph before any mods, skinny tires and loose bushings. Now I can do 66 mph (exit speed at the little bump) it just died!! Bruce
I think this problem depends on the year of the car. The tank design may be different in later model escorts. There was a discussion on club protege about this very same thing, and in my 95 it has happened maybe 2 times but my fuel was so low that it was below the E mark, and it was a like a instant right turn down my street of the main road and not a gradual right hard turn like you may find on a track or onramp.
many people have reported no right turn problems with bosch fuel pumps. IMHO, i'd get the bosch pump regardless of the price but until i can afford it, i'm stuck with this air tex which does it.
With my setup, I can easily have the issue with a 1/4 tank or less. I have done the pump mod, which did help some, but when the fuel is low enough, it can fail and fail hard. I have had it take nearly 30 secs to re-prime and start, but it was a squirrely turn to say the least. I now know what to expect and don't "SCCA" race on the road when the tank is low. I would like to remove sender unit over the winter storage time and see if a baffle or cage could be constructed to prevent this issue in mine. The surge tank is a great idea, as well as a good fuel cell, but I like leaving most things stock and having a 13 gallon capacity.
I really don't want to install a fuel cell into the Pony. It'll add a lot of extra weight and complexity.
depending on the fuel cell you could still mount it where the oem tank is, it seems like i have seen a 12 gal low profile fuel cell on a performance site somewhere. They would be a bit pricey though, especially after installing all the fittings, hose, and ect.
