Changed my carb this weekend to a Holley street avenger,but now the connection from pump steel pipe to carb is very tight,my local parts guy suggested cutting the steel pipe closer to the pump and connecting the two with rubber petrol hose and clips,is this safe what do you guys use? this car has headers and gets very hot down there,i don't want the pipe melting and pumping gas on the headers causing a fire.

ps not with the price of gas over here:D

I assume by "very tight" you mean the distance or clearance is somehow shorter, not that there is a problem with the threads.

Your parts guy's solution will work, with the right rubber line. But I wouldn't go that route. Instead, try bending your existing line a little bit to "free up" a little clearance.

No problem with the threads,just the new carb is dual feed with an inline filter, which makes connecting them together an awkard angle.

I don't know about England, but double-wall, seamless steel tubing is dirt-cheap over here. Easily bent with common tubing bending tools (The single-size units from Imperial Eastman are my first choice, but less expensive multi-size units work most of the time)

I'd just grab some tubing and bend it until it fit right.

"Just" cutting the pipe will cause problems because you will not have the bulge at the end that helps seal the rubber hose behind the clamp. Take the time to get the threaded connections to work, you do not want to mess with a potential fuel leak. Silly to torch your car over a few dollars worth of steel tubing and a couple of hours work.

I agree with these guys. It was a factory thing Ford did in the 70's and 80's. They had steel lines from the carb and the pump. They met on top of the intake and were joined by a 3" piece of rubber hose. The two steel lines would shake and vibrate the rubber hose. Over time the rubber hose crystalized and got hard. It would eventually break and hose the manifold down with gas. FIRE, BAD!

Thanks guys point taken will have to hunt for some steel tubing and and bending tool.Anyone got any photos of how theres is plumbed in they could E-mail so i could get some ideas?

Thanks Mick.

Here is my half finished fuel line project, scroll half way down. http://web.mac.com/zemke2/iWeb/Site/The%20Shop.html

I't custom stuff, and it's in aluminum. Not exactly what you are after but maybe it can get you started.

hey Zeke, I like your fuel transfer system. I live in louisiana. During the hurricanes, people were steeling gas like crazy. My friend actually found a similar device in his front yard when he was cleaning up. Someone was using it to siphon gas from parked cars. I hope I didn't give you any bad ideas. LOL.

Thanks guys.

When I was working as a mechanic, my boss had a similar fuel transfer set-up. He made it from mostly scrap parts and Holley Blue pump from a swap meet. I sort of did the same with mine. I bought the plastic tool box and the Mr. Gasket pump but everything else was laying around.

I actually built that to drain fuel from the old cars to prevent it from going stale from sitting. But after the Hurricane Ernesto turned out to be a non-event I did use the pump to transfer 40 gallons of generator gasoline from my red cans to my cars to use it up!

I hope your buddy kept the one he found, they are quite useful.
