Fuel System

I've got 100hp DAP injectors coming in the mail, wondering if these injectors are gonna suck the fuel and put a strain on the lift pump and then dry out the vp44. Is it necessary to get a custom lift pump? Also going to mount up my fuel pressure guage and wondering where to mount the sensor. I've seen people mount their sensor on the fuel filter, also wondering if it will require a snubber valve as the glow shift sensor is good for 60 psi.

If you still have a stock lift pump then you need a aftermarket lift pump. Search to find which one. There are 3 or 4 threads a week on this.

All fuel pressure gauges need some sort of snubber or needle valve, if you don't run one your glowshift gauges will last a week rather than a month.

a ide rom pressure, what GPH is recommended for each HP level...

a 90 is said to be adequate for up to 600 hp, but most say do a 150 plus.

only because it popped into my head am I asking. I have not searched yet, but curious as to thoughts on this.
