Fuel pump
« on: 30 January 2011, 00:05 »
Been thinking about the fuelling side of the engine recently while reading some other topics and realised that my fuel pump may not be up to scratch or is in danger of failing which could have serious consequences for the engine. As far as I'm aware it's the original one in there and it's knocking on the door of 12 years old now  :shocked:

So I've been looking at the various options, one of the easiest being the Walbro 255 in line pump. I think I'm right by saying this could be added to somewhere like the engine bay as an addition to the in tank pump to improve the stability of the flow.

Has anyone installed one? Would like some ideas on the theory behind it to makesure I'm thinking along the right lines. Hulmie has already suggested some other good alternatives that replace the original pump so there is no need for extra wiring

When using the Walbro 255 inline pump, you still use the old pump as a pick up but the actual pumping is done by the Walbro. There a many options on where to fit it, i.e outside the tank which keeps wiring to a minimum or i have seen someone who mounted it in there engine bay on the side of the cambelt cover. Personally think your asking for trouble if you get a fuel leak in the engine bay.

Here's a fitting guide for a inline walbro

Without seeing his build thread I don't know what sort of power hes running but if your looking to push quite alot then lcr pump just won't do. Luckily for me a lcr pump is enough as I plan to stay around the 300 mark

he's not pushing no where near that so the LCR pump is more than good enough  :wink:

yeah LCR pump is a good alternative, it's just that genuine LCR pumps cost double what the Walbro pump does...

im undecided as yet but think the walbro pump would give the better overall flow rate
