Fuel pressure ?

[Fomoco98]

I need help with fuel preasure.My preasure drops to 20 PSI at high speed and RPM .I need an idea about what is the best fuel pump.Is it the SVT focus or cobre duel setup?

SVT Focus is much cheaper.

Tanks for the input. Do you know the LB/HR on the svt pump

First off....what modifications have you got done to your car? If your car is primarily stock, It may be nothing more than a bad fuel pump.

4.6 DOHC Mark engine ported heads, 24LB injs, Long tube headers, X pipe, 20 Over, Mahale flat top pistons, Tweecer tune, and 5 DEG timing advance across the curve.

Did this start suddenly, or has it always done that since you put that engine in? Seems pretty obvious to me that if it suddenly started, something needs to be repaired or replaced. Focus pump should be fine for your application.

Na I'm still shakin it down and the other night is the first time I really got into it . It starved out at around 125 and FP went to about 20 PSI .I went ahead and ordered a SYT Focus pump today and just debating a regulator. What do you think?

I don't see why not, it couldn't hurt.
