 Posted: Thu Oct 18, 2007 8:35 am Post subject: fuel tank pickup question |
 |
|
Does anyone have any thoughts on why I lose fuel delivery going around a right hand turn when my tank is at 1/4 or less? I understand the fuel is shifting to the side but I am surprised that it does it at 1/4 tank. Could their be something funky with the way my fuel inlet is oriented in the tank? Is this a common problem?

I had a similar issue when I bought my van. I lost power, it bucked and such, when going around a left hand turn. I needed a full tune up with plugs, wires, distributor, filter, the works anyway, and also adjusted the timing (too far advanced), and the problem went away. Mayne it's not a fuel delivery problem. Have you done a tune up recently? Ever?

Have my tank off today for cleaning and POR-15ing it, and I discovered something new. At least it's new to me, it may be common knowledge to everyone else. The fuel pick-up on my 85 stock fuel tank is NOT in the back corner, it's actually right in the middle in that little bump-out you see underneath the center of the tank. There are lines inside the tank that run from the right rear corner where my "out-tube" is located, to this little recessed area. I never knew!!
So, if you're loosing fuel feed on turning, which way you're turning shouldn't make any difference.
Don't think that helps you at all. Sorry, just had to share.

That sounds very helpful. I didn't know that the pickup point is extended to the center of the tank. I thought they controlled windage with baffles. Interesting.
