Good idea to replace the Inline Fuel Filter?

[thesmithsUK]

Presumably it's a good idea to change the Inline Fuel Filter if it's looking particularly dirty?

Don't know when mine was last replaced and it looks like a very cheap job!

If you mean the filter in the base of the pump, these can be cleaned and reused quite easily. If you are referring to an inline filter, these are best left off altogether.

Thanks.

So you'd go straight from the fuel pump to the carb with something like this: http://www.morrisminorspares.net/shop_item.php?ID=2163

Yep get rid of it, they can act as a heat sink and cause fuel vaporisation problems. If anything gets passed the filter on the pump it will settle out in the float chamber.

Nothing shows on your link for me either.
My setup is as standard, just a length of black fuel hose from pump to carburettor. Gives no problems at all.
SU pumps are very simple on operation, and as such the only real risk that any debris can cause is to the float valve assembly, which is easily solved. The system already has two filters, one in the tank, and one in the pump. Adding a third will lea to symptoms as Panky describes.
If it worries you, I wonder if you'd be better investing in a ball type float valve, which is less prone to effect from debris. But I've never seen the need.

Thanks all.

I thought I might remove the dirty old inline filter and replace the two pieces of black pipe with one single piece like this:[frame][/frame]

That'll do the job, very nice

You could always take a trip to your local motor spares shop and buy some fuel pipe, if you a unsure of the size take your old one with you for reference. It will be cheaper too.

Nice article that actually explains the logic that a filter between tank and pump is a bad idea. Better, if anywhere, between pump and carb...

No - you don't need ANY filter. It's just an obstruction and a nuisance. The SU carb copes very well with any particles that get through - not like other carbs with tiny jets that are easily obstructed.
