910 Bosch Fuel pump

[SKY32T]

I just bought the bosch 910 fuel pump to go onto my R32gtst, Man its alot bigger than the stock one. How did you guys attach the strainer on the bottom to the new bosch fuel pump and how do you connect the top hose from the fuel pump to the existing pipe.

anyone got any pics of their install? someone told me i have to buy some earls fittings. True?

Has anyone done this before coz i need a hand hehe..

Thanks guys!

I know this thread is kinna old but no one seem to have responded to it

and Im about to attempt the same thing

I read a few other threads but the pictures werent there anymore

so can anybody lend a hand on a 'how to' install a 910?

i gotta put mine in soon, to make it fit, i was told u have to cut the pipe going down to the pump, so its shorter and join it to the top of the pump with rubber hose and clamps. there shud be lots of info in the search section

the height of the sock when fitted to the new pump shud be same height as standard so the pik up point is the same.

yes: jvs007 speaks the truth

sky32t: if you read the posts a little more closely, it should be covered in there.. basically some thick hose can be used to extend the filter to the bottom of the tank where the original one did sit .. hose clamps can be used to attach the pump and to sit it correctly on the bracket.

You will probably need banjo connectors depend on how your pump comes, which may require a visit to Earls, Enzed, or another hose specialist.

Those threads should be in the FAQ section, in much a lot of stuff should thats trailing down and you have to search for pages and pages to find what you're looking for .. mods!!

I've got a 910 to install as well, but might leave it to the experts, however a 'how-to' guide would be good for a R33 & Bosch pump?

This may also be of some assistance.

There was kind of one, but buggered if i can find it .. Me, JimX and Steve were doing roughtly the same procedure at the same time on each of our cars.

It appears we lost most of the user uploaded pics in November or so when there were a few probs

You're moving down to Brissie sometime soon aren't you? If so I'll be happy to help out if you can wait that long.

/me starts ferrets away on hard drive.. digging up old pix..

[predator]

okz... digging successful here we go.. These were with my old camera so you'll have to excuse the quality. The 3rd photo shows the tank cover with the lid removed.. the 2nd shows the stock pump assembly removed and what it looks like

The 1st pic is how I rigged up the new 910 before putting it back in the tank and putting everything back together again.

Here is the exact thread i was talking about, unfortunately with no photos anymore: http://www.skylinesaustralia.com/forums/sh...00&page=1&pp=25

Basically the procedure is this:

1. Get into boot near battery.

2. Use socket extender with a hammer (tapping) or some ghetto method to unscrew the jaw leading to the tank. This has to twist off (just like a jar top), and is fiddly. Proper way is via a custom tool, however a gear puller may work if you have one.

3. Remove rubber inlet and outlet fuel hoses going into tank. Unclip electrical plug

4. Remove lid, whole pump slots into a bracket inside. Should all come out as one piece, bracket and pump if you pull gently. Can now take it away and work with it somewhere suitable.

5. Remove old pump from bracket.

6. Remove fuel hose from metal feeder hose going to bump.

7. Gently pull off the plastic connector, and sock filter from bottom of old pump.

8. Use sufficient hose to go from bottom of new pump to fit over plastic bit of the filter. May need to shave the old tabs of the filter off. Use small hose clamps to secure top and bottom (shown). You want the distance of the reach/angle of the filter to be able the same distance as the old pump.

9. Connect banjo connector to top of pump. Connect the rubber feed hose to this connector.

10. Secure new pump to bracket. I found that one thick hose clamp did the trick.

11. Slot new pump+bracket assembly into position in tank. Be sure to align filter/draw point to angled left side of the tank (same position as old pump).

12. Reconnect all hoses, plugs, etc. Give it a run with the jar off, then do up tightly.

All of this will make more sense when you actually start pulling it apart.

Warning: Note that I can't guarantee the method I used is a very professional or the "best" way to do it, but after months mine is still working perfectly. I must have got the draw angle correct too as it will go right to yellow fuel light without falling over.

Will not be responsible for your self immolation!! Petrol is dangerous!

It is a good idea to do this when there is not much fuel in the tank

Otherwise you can not see what your doing in the tank if it is full

Predator-

Your first photo shows the stock pump and fuel filter pickup

The position of the filter pickup is in a different location to the new location with the bosch pump.

I installed mine in the same position as the factory height on the bracket, but I have surging problems around left hand corners when the tank is about 1/4 full or less

I am going to remove the pump and try lowering the pickup as per your third photo.

I also had a problem re fitting the new 910 pump back into the tank

I had to mount the pump as high as possible on the bracket so the pump did not hit the side of the tank

This meant I had to cut the factory metal pipe on the bracket out of the way.

Did you have to do this?

Hey Pred! I might take you up on that offer, I'm not to confident when it comes to fiddling with the fuel system and petrol at the same time :flamed:

Moving back at the end of March, will let you know...

[lukits01]

cheers guys

hey suppose I wanted to mount the pump outside without a surge tank

would it be ok to just run it inline with the standard pump

and draw the current by splicing the power wires and running the 910 in parallel with the standard pump?

darrinspenser: yup, this is true I did this I think at the time so that I could position it right down in the tank a bit further than stock as I didn't think it would hurt. The only time I do have any form of surging problem I think the only time this has ever happened when the tank has been nigh on empty, going around a corner hard, etc. You'd probably get that with the stock pump anyhow.

with my 910, I left the metal tube in place (as you can see its almost a bit of a brace up the top there), but its not needed. You'd probably definitely have to remove it for a large pump, 044 or similar.

When I think about, with it fitting back in, I think I recall bending the bracket out slightly a few degrees from where it slots in, and that is probably the real reason for the extra hose length ... to get the draw point in the right position again. I've made a quick diagram of it - so people can visualise what I mean..

lukits01: yup, I believe that is how its done, one pump lower in the tank feeds the other higher up in the tank. The greatest work the pump does in drawing it up out of the tank, so a secondary pump works outside onwards, working to pump it to your engine. I think that is the theory anyhow. You can also do parallel pump arrangements for different reasons. I'm not really an expert on that, so maybe somebody else can help there.

I'm not to confident when it comes to fiddling with the fuel system and petrol at the same tim

Me either really, and I was really cautious the whole way through but i think in the end it is a relatively safe operation (fuel vapours need a good supply oxygen to ignite, and there is not much in the tank)

ARGH!!! I cant seem to get this stupid jar lid off!!

any words of advice?

or is it as simple as twisting it counterclockwise?

use a hammer + block of wood, keep tapping it counter-clockwise. my one was a real bitch to get off.
