Some members are having starting issues.

CS-AR and others have noticed that we are loosing fuel pressure through the fuel pressure regulator, or the fuel injector pintile caps. Some replace the fuel pump, and the check valve it contains. For most of us, the fuel pressure stays where it should, so the car starts, and restarts.

Others still have problems, and are wondering why.

Consider that the fuel hoses in the gas tank can get old .and porous. The hoses in the gas tank starts to resemble garden soaker hose. Fuel and fuel pressure escape through the hose itself, inside the gas tank. Right where we would never think to look.

One of our members replaced the fuel pump , and noticed that the hose seemed soft (perhaps porous) and decided to replace that hose with used, harder hose (perhaps non porous).
The problem went away.

I'd like some feed back please.

I feel that the gas hose in the tank itself could be the cause of hard starting and fuel pressure loss.

if the fuel pressure regulator and the pintile caps are good,
The next place to check would be the fuel pump, and check valve.

The check valve allows pressure from the fuel pump through, then keeps pressure in the system when the car is turned off.

Please replace the hose while you are in the gas tank anyway , replace the hose with fuel injection hose. Eliminate the possibility that the hose it's self is the cause of hard situations.

Our cars are old now. Pintile caps are failing, fuel hose is leaking near the engine. Chances are that the hose in the gas tank is also leaking and causing hard start issues.

 

no you misinterpreted me. I replaced the fuel pump assembly and put back my original hose that was in the car. The original hose was hard and the one that was on the bad fuel pump assembly was soft but now since that hose sitting around and not in the fuel tank it also has become hard just like my original one that's in the tank. So no the hose was not bad and it was the fuel pump assembly that was bad and I threw that **** in the garbage. I checked hose and it's fine with no damage at all.

 

Your comment about the soft hose got me to thinking.

There might be other members out there who have unprotected resolved starting issues.

That might have tried Gibbs usual fides like the pressure regulator or the pintile caps, and still have problems with pressure loss.

If someone is replacing the fuel pump, they should consider replacing the hoses.
They might still have pressure issues after replacing the pump. Due to the hose.

 

No the fuel pump was not bad either it was fine. It's the assembly that pump hooks up to. It's called the fuel tank sending unit which was bad. You have to replace the hole sending unit. That's what fixed my problem.
