No go Maestro Turbo

[John S]

Had a new fuel tank from Rimmers fitted to the turbo and it now sounds like the fuel pump isn't working when the ignition is turned. It was working when I picked it up from the garage but today it conked out after filling up a few metres down the road. It will be towed back to the garage soon, but any ideas?:confused:

[John S]

It's OK, must have been some crud in the system - it's working great now! Sorry about that.

[G51 NAV]

No need to apologise John. Glad it cured itself!

Are you sure the spade conectors are on totally on the pump as it could happen again

Or someone has fitted the feed and return hoses on the wrong way round when they swapped the tank! (Don't ask me how I know about this one!)

[John S]

Well, it started working again as stated but is now a non runner again :banghead:. It will be dragged back to the 'shop soon! I have been doing a bit of wax-oiling with my new fangled electric sprayer to keep me sane in the meantime. I was hoping to put the car back into storage but won't be until this is sorted. Thanks.

This is good advice and might pinpoint to the problem. Will let you know what it was.

[John S]

The car is currently not running due to the carb keeping on flooding and filling with crud. Will this be because I used a petro-seal substance in the tank before handing it over for fitment? Would this render the filter in the tank useless (I sloshed it around the whole tank)? If so, will an inline filter need to be fitted (aftermarket) instead? What would any of you reckon to this?

i woudl use an efi filter on it as the normall aftermarket ones tend to ballon a bit i found that out with monty a while back she kept conking out at 65 /70 mph shes ok now tho got a decent one fitted and she starts and runs like new still:D:D

Definatly check the pipework is on the right way round as this is exactly what mine did when I plugged them in the wrong way round. I was filling the carb through the return line so there was no filter in it!

What tank sealing product did you use John?

Inside the turbo tank is a plastic filter on the pick-up pipe that is imposible to remove. If you used one of those (latexish) products it would block that up.

Also the return pipe inside the tank is in a swirl pot and is also pretty inaccessible to plug up so it could easilly be blocked by some products.

[John S]

Right, thanks for that - shall have to investigate. Pity it's not possible to go the extra mile with protection isn't it!

Agreed John I understand entirely what you have tried to do here mate.:) Looking at the product website its not obvious as to what the tank seal contains, but it looks like it could be the type that would block the tank filter and could restrict the return. I suppose the best bet would be to contact them and tell them what you have, and what you have done, to see what they say.

If it is bad news it could be hard or impossible to save the tank and the other componants such as pump, pressure regulator, and vapour separator.:( I really hope not, fingers crossed:)

Symptoms are:

Balance pipe fills with fuel until car is on boost (connected)

If the balance pipe is removed and clamped the car will run fine for as long as you want it to but as soon as it's on boost it stalls.

Any ideas?

HI John S,

Sounds like the float chamber fuel level way too high, You mentioned before it was flooding so there is a problem with either the carb or the fuel pressure too high (queery blocked fuel return / pressure regulator / Tank ???)

If the balance pipe is removed and clamped the car will run fine for as long as you want it to but as soon as it's on boost it stalls.

Any ideas?

If you remove the pipe from the side of the carb and leave the pipe connected at the carb mounting flange, and clamp the pipe. This would be expected to happen if the float chamber fuel level is too high or not. If this is what you have done then the car probably runs better when not on boost because it isn't sucking fuel through the balance pipe.

I think the tank needs replacing with one of my spare EFi ones, then I'll see how it goes. Just seems a bit drastic to do that at the minute. By the way, had the car back this morning and it ran fine for a bit but now it won't start again!:banghead:

Yes John S, I think that is what I would do first. I would also recomend before connecting the newtank plumbing, run a gallon of clean fuel through the system from one can into another to see if it moves any debris. Then fit an EFI filter inline before you run it again. Sounds like the carb might need to come off for a clean out also. :(

I've given up on it for this year, hopefully when the weather gets better and I have done other things I can make some time to rectify this (I've put the car into storage). I think I will start by swapping the tank over. I guess there's no point getting a mechanic to look at it again until a non-suspect tank is fitted.
