Bike Carb Fuel Pump Q
Dick Axtell - 24/9/17 at 02:24 PM

....And another question for the LCB think-tank!

This is addressed mainly to those of you who have fitted bike carbs to your 4 pot car engine. Has anyone successfully fitted an in-tank fuel pump, for use with bike carbs? If so, which pump did you use?

My existing bike carb (external) pump can be fitted, but there will be no space for a filter. So an in-tank pump might be an option - maybe??

What ever you do , do not use this one: Huco pump

Bogg brothers laughed at it.It was pulsing fuel drops by drops. Well not drop by drop but little squirts at a time. What did instead of use standard car fuel pump and put a regulator with a return feed.

Just get the pump off the bike that the carbs came off..

Only that newer fuel injected bikes have an infant pump.

Land rover do an in tank pump for the v8 with su carbs which will do the job and is very cheap as well.

Land rover prc7020

Google it....

Coozer, thanks for your very helpful advice.

That confirms one of those doubts I had pondered.

Thanks also, bikecarbfred, for the heads-up re Huco pump.

Why would there be no space for a filter with a bike carb pump?

Bike carb pumps are gravity fed (force pumps). Which means that the pump inlet has to be at the tank outlet level. On my car, there is very limited space, to keep pump inlet, tank outlet and in-line filter all on the same level.

Put the pump under the tank?

Which would entail raising the tank. This will impinge on other equipment at the back. Not an impossible option, but one with added problems. Will look at these in more detail.

I mounted mine on the scuttle with no adverse effects.

I did the same and though it worked fine, after some time I had a situation where the pump wasn't switching off. I think this was possibly down to air being drawn in somewhere along the pipework between the tank and pump.

I moved the pump to the back of the car and the problem never resurfaced.

I've had a couple of the Huco pumps with no problems.

Try a a zx6r carbed fuel pump. Has a 90 degree outlet - https://i.ebayimg.com/images/g/RJwAAOSw7NNT4kEY/s-l300.jpg
