Blowing Fuses on SVO Fuel pump
I am stuck and looking for some advice. I have a 6L with a Mallory 110FI Fuel pump pulling vegetable oil from a second tank. I am using it with a regulator to push the oil at 65PSI. The unit was running great all winter but since it warmed up has been blowing fuses after about 30 minutes of running. I checked all of the wiring, ground, relay etc. I ran 12 gauge wire again. Nothing.
I am wondering if the pump has gotten too hot and is toast or if there is something else I am missing. I am pulling through a heated 5 micron filter. The regulator bypass back to my tank. It has worked great for about 6 months though the loadness of it drives me nuts. I will check the amperage draw tomorrow. Mallory says 12amp draw typical. I have a 30amp fuse in place and a 50 amp relay. Thanks Torie |
pump worn out !

Amp draw was about 50!!! Must have gotten too hot?
Does anyone know whether these can be rebuilt? |
The Mallory is not up to the task of pumping WVO - especially cold oil.
The only decent option is the FASS HPFP, but even it is known to have a relatively limited lifespan in VO service (mine have run 40-60k miles). FASS will rebuild them for about $125 (usually :-roll) when the motors finally burn up. Hopefully, BFT/Vegistroke - forum sponsor here (previously DFA) - will make a stand-alone version of their superior-to-FASS Scorpion Pump soon...

The regulator bypass back to my tank. FWIW, alot of folks were using Mallory and Aeromotive fuel pumps when I did my conversion - after talking with several of them and realizing they had a huge pile of junk ($400 :eek:) pumps between them, I decided to just use a stock 7.3 fuel pump. At least it had a no-questions-asked warranty at local autoparts... I ran it without any issues for the first 70k miles on my conversion. This pump does not like restriction on the suction-side though - I'd recommend putting filter(s) on pressure-side (post regulator, so ya don't filter the fuel but one time ;)). Just use a screen/strainer pre-pump to protect pump from a pine needle or leaf that may fall in your tank while filling. |
I am useing the AirDog Raptor 150 with good results so far. Jason over at WVO Designs has built an even better pump designed just for SVO.
