I installed a Bosch 910 pump over the weekend, car was running fine after a test drive.

However on the way to work this morning the car stalled at the first intersection, and wouldnt start again.

After getting it home I pulled everything out to see what the problem was. I found the pickup had fallen off and was somewhere in the tank. I couldnt feel the bugger anywhere so decided to give up and let a pro do it.

So I get a call from the workshop today and they tell me that I shouldn't have used it internally, and that it was very dangerous?

There are allot of people using these intank, is it safe to use?

I was running a Bosch 910 in-tank up till the end of last week. It had been in there for almost 4yrs and came out still in tip-top shape. It's now going into an RX7 turbo circuit car. The only reason it was replaced was due to it not handling the demand placed on it.

EDIT: Didn't read your above post until after I'd added the below info....

How is a Bosch unit any less safe than the stock pump is replaces? They both require power and earth connections and unless I'm mistaken they both have the same kind of construction. If it was an unsafe practice then A LOT of workshops are up for serious legal issues!

Mine has been 8 months i think.. i think you stuffed the pickup mate :D its got to go in exactly the same position as stock and erm, not fall off. How much fuel you have in there?? Even if the pickup has fallen off, if you have 1/4 of a tank it should just suck straight in as when the tank is full its fully submerged

Shouldn't be too hard to find.. during daylight with a torch could see inside most of the tank. But i do have skinny arms. ]

Did you use a hose on the end to extend the pickup and get the placement right? Some rubber can go funny with petrol and expand, releasing the item - hence the hose clamps tight as buggery

Wouldn't be dangerous.. might stop working yes, dangerous no.

Had about 1/3 a tank and yep I had some hose on the end (was using your pic's as guide) and that was still attached when I pulled everything out. But come to think of it, it was a little out of shape, so maybe I bought the wrong hose... Silly me!

I didnt want do it up to tight as the end of the pickup was plastic and didnt want to break it with hose the clamp.

Dunno whether to try again with the Bosch (and your help) or get a GTR pump?

Hmm, well I'm confused?

I have an '0 580 254 910'.

He said I need an '019', for in tank applications, and this was apparently confirmed by someone at Bosch too.

:confused:

Edit: According to http://www.bosch.com.au/sat/motorsport/dow...s/fuelpumps.pdf there is no 019.

Many things aren't used for their intended use.. but work fine.

Many have no issues, and many follow the manufacturers guidelines a little too heavily. More to the point, they probably would prefer you to pay the extra for the intake one.

Many people say "yes" and many say "no"... but whatever works works. It worked for me, and seem a few others on the forums here.

But if you feel safer with a GTR or the intended "intank" one, change it for one of those.. i'll help you install, now you know how to do it that is most of the work done.

The issue here i don't think was the pump failed due to being "intank" or not at all anyhow, it was the pickup falling off.

p.s. i'll buy your stock pump in a month or so too :D

Its all good!

Apparently earlier pump models e.g. where not supposed to be used in tank at all. But newer revision models are fine for in tank applications.

The workshop was going off old info from previous models apparently? Or maybe there just covering there ass? Anyhooo I'm sticking with the 910. But my pickup is lost in tank blackhole :)

as long as you run over 1/2 a tank all the time, you should be right until you can have some time to find the pickup. With a torch you should be able to see inside. There is a small indent where it is meant to sit inside, maybe its sitting down the bottom of there?

No luck unfortunately, I've jammed my skinny little arms all the way down as far as I can, the workshop couldn't get it either.

They said I can get Bosch specific pickup that will fit on their pump correctly anyway ;)

I was running on an 1/8 this morning, so they must have put some form of hose pickup on the end.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
