Hey peoples!

Here's my dilemma: while testing a new Walbro 255 for operation (touching leads to battery terminals) for maybe 10 sec's, it begins to get a bit warm (not too hot to handle, just warm).

Is this normal and how warm is safe https://www.nopistons.com/forums/pub...R#>/unsure.png ?

Knowledge me...



Props in advance!!!

Are you putting fuel through it or just air?



I would think running air through it wouldnt be good?

Just running air through it... checking it for noises, retarded vibrations and such.

Fuel is the cooling medium for a fuel pump. The heat generated is normal but you should avoid running the pump in the manner you did for any lenght of time.

Thanks for the input. Much appreciated.

nevr run a pump dry, it will kill it!
