I did answer that.

Yes provided the intank pump is in good working order, you have changed both the fuel filter under the car, and the filter sock on the untank pump, it should be fine.

However I'd suggest if your car has high Kay's or many years old now, it may be time to change the intank regardless.

I have seen early Ba ones fail (as Long as 4 years ago)

But is saying this. 99% of the time the intake should be fine, especially of you already has mods and more than 13psi boost.

Thanks Headsex , I only realised there were 3 pages to this thread after I made the post ( idiot ) .

True, I've got 2 o44s and a custom 4lt surge tank I've mounted in the spare wheel well, even though I used the speed flow fittings and line there is still the smell getting through, which sux so I don't recommend it to anyone, but in the upside, E85 doesn't smell so there's no smell issues, and o44s run so cold with e85 they are very quiet... It's amazing how loud they get if I have to use 98, takes about 15 mins for them to heat up and buz like mad.

It's good to see fuel pressure has been mentioned, as the pressure is as important as volume.

Here's some simple theory...

Injectors need a certain volume of fuel to flow x amount for the motor to make power, and the volume needs to be controlled by pressure, this pressure is set in the rail, and controlled by the fuel regulator.

IF the stock pump is the only pump in your system, it's the low tank level pick up that greatly reduces the fuel pressure, so less pressure equals lean lean lean afrs, and usually damaged motors if constantly pushed through this lean area.

If your budget does stretch for a surge tank set up, I'd get a fuel pressure gauge , perhaps with a warning light or buzzer, atleast you'll have a warning to tell you to get off the throttle befor you do damage.

Now the stock reg is good, mine is still working fine at 460wkw, but what I've found is that boot mounted pumps supply less pressure at the rail, compared to pump(s) mounted in the enging bay.

This is the reason why slot of guys running 2 044s in the bay have run into idle and cruise issues, as Danny mentioned , super rich mixtures due to the factory reg not being able to flow enough fuel AWAY from the rail.

Myself & CMS have set up quite a few Plaz surge tanks with aeromotive a1000 pumps and haven't had these low rpm fuel mixture issues, so I'd say the 044s , being higher rated (1300 v 1000) push just that little bit too much volume and pressure for the stock reg to flow... Where the A1000 is just enough for the stock reg to flow.

Even though my own car runs 044s in the boot, I much prefer a front mounted surge tank and Aeromotive A1000.

I've got 80s flowing enough E85 for 460wkw, on stock rail pressure, but close to their limits at this pressure... Though we have seen high 500s from 80s but running 95psi rail pressure which is a bit to high for a street car.

Hey Chris do sell any PM or PW surge tanks ???!!

if you do will consider a group buy on them for cheaper !!! I think a lot people be interested to buy one !!

J.D. customs still make cheap curge tanks?

Do the single 044 surge engine bay setups have this same issue?

nah man I spoke to them couple weeks ago for one not much cheaper! ill rather pay bit extra to get pw or pm instead if comes to that

Group buys on these have never got the price down much. Just ring up Alex from plazy and see what he can do it for. Usually does a good price.

If you had an FG I'd say buy mine. I want a twin pump setup
