Fuel pump help, Please Options

[gster]

I've installed an Airtex pump on the car as recommended by many.
The car does run but terribly....
I hope I've installed correctly and put the "T" adapter in the right place.


The fuel line from the tank goes to the filter then to the pump.
The pump output line is then T-eed to the other 2 lines....



Have I got this wrong?
Is the filter restricting flow?
The car has been sitting awhile and I've put fresh gas in.
Otherwise nothing has changed.
Any help is appreciated.

The Fuel pressure regulator in the engine compartment dumps fuel to the fuel return line back to the tank. The 3 port fuel pump also has a pressure relief valve that can dump fuel to the return line to the tank. The return line from the fuel pressure regulator and the pressure relief valve on the pump are "T"d together near the pump.

If you replace the 3 port pump with a 2 port pump you eliminate the "T" fitting and the old line from the pump to the "T". The return line from the pressure regulator goes straight to the fuel tank.

You should also be sure you are using fuel line rated for Fuel Inject pressure and the ethanol our gas has these days, J30R9 rating I believe. I have not seen any cloth braided fuel line that is rated for I pressure.

Yes they do make braided FI line, BUT I wouldn't use it because of methanol fuels. In fact I won't use it any more because it's poor quality and begins to crack in as little as one year.

Only use SAE 30R9 rated fuel hose and FI hose clamps
Gates Barricade hose is a good brand. Do not use standard worm gear hose clamps.

Even with good hose I'd recommend replacing it about every 5 years.
