Outer Limits 4x4 Board

have you ever dinted a return fuel line, or had something blocking it off.

What happened?

Did the car run like crap, backfiring, flooding?

I cant see any blockages or dints in the lines.

If i do replace them, do i need to use the metal fuel line, or can i use the rubber line. It would be about 2 meters long.

Thanks in adavnce

I would prefer to use a metal line.

But a dint in the return line would have to be massive to cause overpressure.

I would suspect a blockage if you can't feel any dints. They can happen.

can you get to where the return line enters the tank if so disconnect it and see if its flowing

Or, I meant to say, a completely different problem altogether causing your symptoms.

well thats the thing.
the car is runing rich, I've played with the carby, even put a rebuild kit thru it. The timing is running crazy adanvced, but thats the only way to get it running.

I thought it may have been the fuel lines, so i swapped them over and when i undid one, there was alot of pressure in there. Now keep in mind that i've got a gq 42 with a carby. so i wasnt xpecting for there to a heap of pressure in the return line, when the engine wasnt running.

After i did this, it ran great for about a day. now tis back to being a so and so again.

So i was just wondering, if anybody else had dinted one, or had a blocked one, to see if what the issue is with mine is the same sort of thing.

I think i' know what i'll be doing tomosa night. I'll pull the drawers out, and get to the fuel tank, start there with a peice of fuel line, and see if it make a difference. If it does, Booyah, i'll buy some fuel line and make it up to fit as it does now. if not, i havent wasted too much time and money. Well money so far.

might be a silly question, but have you checked the fuel filter???

Disconnect the return line from the carby end and the fuel tank end. Have someone monitor the fuel tank end of the hose with a clean rag held loosely over the end of it while you blow compressed air into the hose at the carby end with an air blower. See if a: it blows air freely through the hose and b: if there is some restriction, are you getting anything in the rag.

put a fuel pressure gauge on it. any more then 3psi is to much.
