Speaking to the shop that previously dyno tunned my car they said that they left the previous owner with the recommendation of an upgraded fuel pump (255lph) and a upgraded alt (140amp).

I know the alt was upgraded (I can see it) but the fuel pump is a tough one. Is there any way to know what pump I have without dropping the tank? I can't get a hold of the previous owner.

I'd hate to put it on a dyno just to find out that the pump wasn't upgraded and waste some money.

Thanks.

It's kinda hard to tell from this standpoint. [8D] I guess if theres no 'in-line' pump underneath your car, than it's probably safe to say that you'll have to pull the tank. What kind of numbers are you makin?

I don't have numbers. I'm going to meet the tuner today and look at what they did on the last tune. Over the phone he said that it was getting lean above 4800rpm and that he did not want to push it so he left it there and told the previous owner to upgrade pump and alt.

The previous owner when I was buying the car said it has a 255lph pump in it but I can't know for sure. I'm pretty sure he wasn't pulling my leg but who knows.

Can I just lower the tank and tell from the top of the pump or do I have to pull it out of the tank?

I'll post more when I get back from the tuners.

Thanks.

you gotta pull it out, but its pretty easy.

This is what the shop did last year with the previous owner.

They stoped at 4800rpm because it was getting lean. At 4800rpm it made 231hp and 265tq at the wheels.

I'll post the diagram tommorrow.
