I have a TPI conversion project going on, on my 87 Camaro 305 carbed engine.

I have bought a complete TPI setup and all the wiring harness I need.
also the ECM is on my shopping list.

I know I need to change out my fuel pump. What kind of pump should I buy.

I have 2 pumps I have been looking on.

190LPH In-tank Fuel pump

255LPH in-tank Fuel pump

I know the pump on 190LPH is more than big enough now for what i am converting my engine to. But I was thinking of in the later time, mayby I will do a little bit performance and then I need to change again to a bigger one.

My main question is: What happens if I buy this 255LPH fuel pump now on my car and just have a stock setup?..

Would that be wrong?...Better with the 190LPH pump mayby??..

 

Excess volume will be returned to the tank by the pressure regulator.

 

It all depends on what you want to do, i just went through this and decided since i wasnt going to make my car a monster or anything, i would get a 190, i got a walbro 190 from a guy recomended to me on here, cost me 83$ and got it in 3 days. He also sells the walbro 255, for around 100$ i think, comes with the harness and everything. I was told that unless i was going to be doing anything radical with my car, a 190 would be more than sufficent. If you know what you want to do to the car in the future, than we could make a suggestion of getting the 255. If there is any doubt to what your going to be doing look at it this way, you only want to drop that tank once.
