Me too! First, if you haven't, run 20w-50 oil, I got a 2-3 psi boost from this over a 15w-40. If you still have low pressure, run straight 50w oil, it's physically thicker (actual viscosity) than a multi-weight, which is what you need for a loose engine. These are considered racing oils, and Valvoline makes one, among others.
Very temporary extreme measure. Get that engine fund built up!
Good luck,
Stuart

So to be clear, I'm adding the higher volume pump to keep the engine going for a few more months.
I'm still saving for the motor replacement next year. :)
