The mechanical standard type pump is just there for redundancy... in case the electric pump craps out at a inconvenient time, which is always the case. A Drag week type event is still on my bucket list. I want a built in backup on everything I can think of failing to save time and a possible DNF. I’m looking at belt driven pumps also... thanks
The mistress has already basically tied its best ever pass on race gas with the methanol change over, runs cooler, almost too cool this time of year, took a bunch of rear gear away also, so I know the 520 is making a bunch more torque. All this while starving for fuel, so I’m hoping there’s a tenth or three left in it yet.
