Fuel trouble
Hey guys,
I've got a vortec 4300 from a Chevy silverado in my 69 CJ5.
I've got a walbro gsl 392 fuel pump in it.
Walbro GSL392 Inline Fuel Pump 255LPH HIGH PRESSURE (universal external pump)
The fuel pump has never sounded great, it whines a lot and is quite loud, part of that I just thought was because it was an inline pump on the frame right under me.
But now I'm having a lot of trouble with idling and stalling. It's always been a rough idle, but lately I have been stalling a lot at idle.
All of the fuel lines are new and there's a new fuel tank which is only four years old. I just put in fresh gas and a new fuel filter. No better.
The next part of my troubleshooting I was going to replace the fuel pump.
I had put the fuel pump in before putting a new fuel tank in. The previous tank was pretty rusty and I'm afraid that the bad gas damaged the fuel pump.
My question for the group is should I put in the same fuel pump? Or are there any other thoughts that I can troubleshoot first? I do not have a fuel pressure testing gauge.
Putting in the same pump would be easy because all the fittings are already there.
Thanks!
