Thanks for your thoughts on this.
I am going to run without one now. I will pull the pick up out of the tank just to check the gauze, but as it is running so well at the moment I don't think there is a problem in the fuel system.

Hi all,
What is the correct fuel pressure with the standard fuel pump ? ( the one with the glass bowl )
Would it be advisable to use the diesel engine fuel pump.? Fuel pressure is higher right ?
How about using a electric fuel pump ?

Thanks.

The standard original glass bowl type AC fuel pump does a pretty good job of filtering the fuel without any help, however the later type without the bowl and electric pumps do need a filter. When I fitted an electric pump to the ambulance I got a glass bowl filter from somewhere, Holden I think it was. The Solex carb has an additional gauze in the fuel inlet union which is nice, sadly lesser carbs don't have this. Can't say I'm a fan of those plastic inline things.

I use one of the little glass efforts that can be taken apart and cleaned, so never needs replacing. It seems to work very well. I run a 32/34 DMTL twin choke weber, and I wouldn't want to run without a filter as they're massively susceptible to blocked jets.

In my experience as long as they're good quality and regularly checked the little inline filters are OK. I've had one poor quality ebay one drop in half on me, I think the fuel dissolved the glue holding the thing together ::)
I also read somewhere of one causing running issues. When the car was initially started it would run fine for 5 mins and then cut out. It turned out that the filter was fine initially but once fuel started flowing the paper element would swell restricting the flow of fuel.

Hi Darkside
Given my recent dramas with fuel supply (or the lack thereof) please see my other post.
I removed the in-line filter I had installed for the Webber and have now replaced the Webber with a Zenith 36IV. Removal of the filter "helped" a little but did not cure it.
So I guess what I am trying to say is if there is any weakness in the fuel delivery system then the in-line filter
will restrict the flow.
Hope this helps
Cheers
Alan

After seeing the **** that my filter has stopped I will be keeping mine. Especially after spending £100 odd quid getting my carb sorted. Also means I can see when fuel is getting up when hand pumping (vapour lock issues)

Weber advise the use of a filter with their 34ICH
I've had filters on for 30 + years without issue on quite a few Land Rovers with every standard car that Land Rover ever used on a Series and also an SU and have never had a problem.

Haven't had drama with them and my SU :-?

I know with mine when I was running it a daily on a webber I was cleaning the jets at least once a week. I fitted an inline filter and I've only done it once since.
That said webbers are **** for getting blocked.

Evening.
I have been running my 2286 petrol with in line fuel filters as I had an endless supply of them.
However I am becoming convinced that they are not helping the thing run as sweet as it can. It does seem to run better without one.
I have a Zenith carb, the lift pump is in good fettle. I just think that they are restricting the fuel flow, particularly at low revs.
Does anybody have any thoughts on this?
