Which fuel pump?

[Simon Smith]

I keep wrecking fuel pumps. I've got through two Pierburg pumps this year. They haven't been run dry as far as I know.

So what pumps do you use and which ones are reliable and cheap?

This is the fuel pump we use.

This is for a GSX-R600 K7.

We have never had a problem with it.

We have it regulated to 3 bar.

Cheers,
I'll try one of those.

Don't think its the pumps that are the problem, more like the fuel you are using, also drain system dry between meetings that will also help.

Do you have a filter between tank and pump?

Pre filter too fine?

[Simon Smith]

I'm using Vpower fuel with an inline filter between the tank and the pump.

I've never drained the fuel between meetings though.

[STEVIEBOY491]

How often are you changing the filter? Are you sucking in air on the inlet side, I.e. running it dry? I had this problem, changed to screw connector instead of bayonet and jubilee clip. Too fine inlet filter? Too powerful a flow rate?

So many questions!

What regulator do you use?

Had Pierburg pumps on for year . That and bosch pumps . Id suggest there maybe something not quite right with your syatem possibly if youve knackered 2 . And ive never drained fuel out either . Could understand if it was methanol or something but pump fuel wont hurt it

Thank you.

What regulator do you use?

Joe uses his own home made system, limiting the return flow... That could work too...

Theres a lot more pressure with a fuel injection system Marc. Simon you seem to have a system that most use. We certainly have something similar and have had no problems and we use Sytec pump which some people have had bother with. Our pump runs off the ECU would that make any difference ?

[Whites]

Our pump was an internal one, we changed this as we changed the brakes and needed a new fuel tank, so we went for the pump and regulator I linked above.

This is how we have it setup;

Code: Select all

Tank --- Filter ---- Pump -----------Throttle Bodies
 |                              |
 |                              |
 |                              |
 |-------------------------- Regulator

We did have a few problems with fuel starvation at the beginning of the season, but this is because we origionally had the return of the regulator going between the filter and pump, instead of back into the tank.

We still get this occasionally, but we believe this is due to surge when we have low fuel.

We wired the new fuel pump to the original wires that ran the old fuel pump.
