What was the minimum fuel pressure for a GMC Savana?

What was the minimum fuel pressure for a GMC Savana?

This engine required 12 lbs of fuel pressure per square inch. The minimum flow was 29 gallons per hour and the minimum current was 12 volts. The fuel pump was located in the gas tank. From 1987 to 1996 the GMC Savana used 5.7-liter eight-cylinder engine. The fuel pump for this engine required 12 lbs of fuel pressure per square inch.

What was the minimum fuel pressure for a GMC Caballero?

The minimum flow was 29 gallons per hour and 12 volts was the minimum current requirement. The fuel pump was located in the gas tank. The GMC Caballero used a six-cylinder 4.3-liter engine from 1986 to 1987. This engine’s fuel pump required 12 pounds of fuel pressure per square inch.

What was the fuel pressure on a GMC pickup?

The fuel pump required 12 lbs of fuel pressure per square inch. The minimum flow was 29 gallons per hour, while 12 volts was the minimum current requirement. The fuel pump was located inside the gas tank. Fuel Pumps: 1985-1990 GMC S15 Pickup Fuel Pump 4 Cyl. 2.5L (E) T.B.I.

How to check fuel pressure in Ford Sierra?

Check the ISCV before – the usual, wash it out with carb cleaner. Maybe soak for a short while with brake fluid. Check the end cap for a ‘X’ stamped in it. Those are the later valves. The early ones were a bit prone to clogging. Location: I dunno man – i only just got here meself!

What should the base pressure be on a GM return system?

With a return system, the base pressure is set with the engine off, but the pump running. For a GM, this pressure is usually set to 58psi (factory fuel pressure in the rail). The vacuum/boost referenced regulator will help to change the pressure in the rail based on the pressure in the manifold.

What’s the fuel pressure on a Vortec 5300?

Now got all lean and rich fuel codes (p0171,072,074,0175). No vacuum leaks- thought dealer mite not have tightened an intake bolt or something during engine swap. Thinking maybe fuel pump.checked fuel psi- been running at 43psi!?!?

Why does fuel pressure rise when idling at 20 inHg?

When idling at 20 inHg, this means effective pressure will rise to 68psi because the vacuum in the manifold is adding 10psi to the rails 58psi. This requires injectors to pulse shorter so as to not overfuel the engine and cause a rich condition.

What should the fuel pressure be on a LS-1?

Thinking maybe fuel pump.checked fuel psi- been running at 43psi!?!? I have 2 ls-1’s in other vehicles and they won’t run below 52psi,which is what I’m used to.i run lingenfelter Asa racing pcm’s in those vehicles, but 56-58psi should be good for all ls. Maybe 43psi is something new do to fuel on demand pumps with no return line?
