lift pump install

[hoghead]

Installed lift pump no leaks so far but the leaky fuel heater is now leaking worse I guess from the lift pump actually holding pressure instead of leaking like it did before. The parts are on the way for leaky fuel heater. Question is am I right to think that my theory on the fuel heater leak is correct. When I get all these leaks fixed will I have more throttle response,power,or fuel economy.

If your truck, engine is the average daily driver, you will notice no difference. If your on the dyno, you may.
If you have a fuel pressure gauge, it may be up depending upon how much fuel your loosing from the heater.

I would have removed the heater if your not in very cold climate.
