Hi,
I'm wondering whether or not it's acceptable to rely on an inline fuel filter (universal) as the only fuel filter on a car?
The car in question is a Bentley S1 (twin SU HD6's), and the original filter assembly is damaged and expensive to replace.
I can bypass it fairly easily and install an inline filter, or maybe two (before and after the pump).
Thanks in advance!

My car does not have anything else but a universal inline filter as standard, neither does my dad's MGB, or most other old cars I've seen. Doesn't mean I'd dare to advise you it'll be ok for your Bentley, though...

Usually the filter goes after the pump, some don't work properly with it in front, there shold be a gauze or something similar on the tank pick up to stop larger particles damaging the pump.
Any fuel filter will be ok but if you want soemething a bit bigger capacity than the little plastic ones get one for something like a mondeo at around a tenner.

early 106/306/zx filters are decent inline units, 8mm barb each end iirc, pretty cheap.
doesnt matter where it goes specifically, just between tank and engine on the feed side.

IMHO it should do the job. What kind of fuel pump is fitted however?
One thing to bear in mind however is that it may affect resale value. A friend of mine who went down a similar path albeit on more parts on his MKI Triumph PI really suffered because of this come sale time and moaned of timewasters etc. In the end he got £5.5k, a cheap price for a very sorted Triumph Mk1 PI saloon replica rebuilt from the ground up with no rust. That however applies for any modified car.
Just how expensive are we talking for the part?

I run mine with an inline before the pump - works fine.

Thanks for the replies everyone.
I'm not too fussed about the resale value, I'm going to bypass the original filter so that it can be reinstated if a refurbished one is bought. At the moment I just need to get it running reliably!
The fuel pump is a brand new genuine SU model, the correct one for the car. I'll try an inline filter and see how it goes.
Thanks again

Ah fair enough, so the fuel pump can do the regulating in that case  . |

Hi, carbs are a lot more forgiving than fuel injection as far as filtration goes.
