capri fuel filter

[wedget]

From what i understand the fuel filter on my 85 280i is from a capri,

1. why is it so big

2. can i replace with a normal in line filter

3. any ideas if a normal capri 2.8 one will fit

4. forgot the other question

I am extreemly skint at mo. and someone told me the filters were about £90 seems a lot to me when most other filters are about a fiver. any ideas would be hugely appreciated

5. why is there no spell check on PH...!!!

For what it's worth, my (US) 280i uses a very generic filter (about the size of a large oil filter). The WedgePages [url]www.tvrwedgepages.co.uk[/url] lists a Fram G7344 which I crossed to a Bosch, maybe 35 USD.
Maybe someone super-sized yours, but if everything else is stock, you should be able to go back. Grady

One of the reasons that the filters are expensive is because the filter is pressurised to injector pressure. This is in the range 20-50 PSI.
I think the cheaper filters are for carburettor installations where the pressure peaks a lot lower.

You could always go aftermarket.

This is a better shot....


Bravo Andy I really want to see your car

Does the second photo show a filter fitted to the fuel pump suction line? If so please advise type and source.
I have tried a couple of different filters in this position but so far all types tried do not flow enough fuel. The engine gets starved of fuel at higher revs, particularly with fuel tanks less than half full. (Removing the suction filter restores performance. Fuel pump is new)

Fecking hell, you keep your car nice... My fuel filter is under the bonnet, mine is a v6 will the £20 v8 one do the job or will it be better.

Cheers Dicky, the underneath is probably better than the outside at the moment though!

Hi Hamish,

Have you got yours back together yet?

I got the pre pump filter from: www.fuelsystem.co.uk/Default.htm
Had to give them a call to get it ordered though.

When I replaced the swirl pot the original had a small gauze filter in which couldn't be re-fitted in the new one, and with the amount of solder that was in there from the tanks I thought it was better safe than sorry!

i went to halfrauds at linch time and was told £15 for fuel filter, this it the one that goes under the bonnet.. What is the thing next to the fuel pump under the car by the rear wheel is this the "swirl pot" and should this be changed instead of filter as my car hesitates in high gears at high revs

[AM400]

The swirl pot is fitted between the tanks, you can see it by the upright on the picture. The blue thing next to the pump is the high pressure filter, the red one before the pump is the pre pump filter.

I wouldn't worry about the swirl pot unless it is corroded badly, this was the reason I replaced mine.

The filters I used were expensive but can be cleaned so should work out cheaper long term.

I really dont get this, my car hesitates a little in high gears at very high revs, someone sudgested replacing fuel fiter... but now i am confused is this the filter that is under the bonnet and costs around £15

[chris280]

The fuel filter under the bonnet is a consumable and should be changed every 24,000 miles or 2 years according to Ford. I suggest that you replace this one first.
I had similar problems with mine when I first bought it and found that the filter was so clogged that there was virtually no fuel getting through, just enough for the car to run and idle but it would cough and splutter as soon as you touched the accelerator.
Hope this helps.

On my 280i...

There is a single alloy fuel tank, and no swirl pot ( a bit of genetic diversity is good right?)

According to the Haynes manual, the extra cylinder is a fuel accumulator...

" The fuel accumulator has two functions, (i) to dampen the pulsation of the fuel flow, generated by the pump and (ii) to maintain fuel pressure after the engine has been switched off. This prevents a vapur lock developing with consequent hot starting problems"

I have replaced the fuel filter and it has made no difference still hesitates over 5000 prm in 3rd 4th 5th could it be since i changed to optimax from LRP seemed to happen at the same time, have tried going to BP ultimate to see if this sorts it. but any other ideas are most welcome

[jchase]

So what RPM do you go to in 1st and 2nd then ?

And the air induction system is bog standard stock, no air-ram intake or free-flow filter fitted ?

A little experiment you could try would be to see if the speed of the car is the dominant factor as opposed to the engine load. Ie. get up to cruising speed, where 3rd gear would be at 6000, stick it in neutral, and just see if you can rev the engine to 6000 rpm, when it is not doing any work. If there is a wierd air-ram effect going on this will show up, as the engine will lean-out and mis-fire.

Haynes manual, diagnostic section says:

"Unsatisfactory road performance ... System fuel pressure incorrect"

..not a great deal of help really..

I do have a K@N air filter fitted revs up perfectly when not in gear and is only a minor hesitation in higher gears.
