Chevy & GMC Vans

Hey folks,
I have a 95 with fuel injection. I've just had my fuel pump poop out and in replacing it I found EVERYTHING was rusted to crap. So I'm replacing it all from the engine back. My questions is the the connections at the tank and in general. The connections on my tank are 2 rubber vent lines and 2 flared connections (3/8in and 1/4in) with o-rings. I've gotten the lines I need that are the same GM number as my 95 from a salvaged 91 but it's carburated and not under the same pressures as FI lines and the lines end at the tank in a rubber hose and band clamp. Mine has the vent fittings but the feed and return lines are flared connections. Can I use reinforced rubber fuel line from the tank to the steel lines and secure them with band clamps or do I really need the flex line flared fittings because of the pressure (something like 126psi?)? And it's been really, really hard to get the steel lines and flex lines from anywhere so I turned to the salvage yard. Here in Texas the 91 was clean and pretty.., unlike my Wisconsin 95. Anyone else experiencing this problem of fuel line availability? And did I make any sense above? Thanks.

There is rubber hose that is known as fuel injection hose you can get from your local auto parts store.Also there is hose clamps the isn't the kind the tightens from the side.That doesn't apply pressure all around the hose.You want either a clamp style the you close up by crimping the clamp or the style that has a center screw that applies pressure all around the hose.

The 91 you got parts from wasn't carb'd unless someone swapped and engine in there. It was probably TBI which means the system only had about 12 - 15 psi. Your 95 runs between 50 - 60 psi. I would be very careful running regular hose. Make sure you double flare the steel line where the fuel injection hose connects to make sure it doesn't blow off. Last lines I bought was 5 years ago and they were available then. Not sure about now.
