Holley Red fuel pump current draw

Does anyone out there know what current a Holley Red fuel pump draws?

We are using it to pump ATF (on the gearbox cooler) rather than fuel, but this should not make any difference.

easiset way is to hook up an amp meter, but make sure you check it under load (pumping the atf) to see what the max current draw is.

My ampmeter only runs to 10 amps, and I am not sure if this will be enough. I am intending putting a circuit breaker in, but had considered putting a fuse in as a temporary measure and increasing the size of the fuse until it does't blow, but figured that someone might know and it would be easier to see if I could find them.....

With a Holley Blue they recommend you use a 7.5 amp fuse, so a Holley Red should be about the same.

Do's it say how many watts it uses?? divide by 12 = amps..

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!

Actually you should divide by 13.8 as this is the alternator output voltage.

What about voltage drop? The Fuel pump is not connected to alternator. Keep it simple geeze !!!
