Need help with 68 Bug

yes, it can, but I wouldn't if you are running a single centermount carbureter, stock or otherwise

you shouldn't have the filter on the pressure side of the pump.. that said, it's normal for the filter to have very little fuel in it...

there's really not a best... why the desire to switch?

What Joey said.

1. Why block the preheater?

1. filter goes on the suction side of the pump, not the pressure side. A dirty filter is full of fuel, while a clean filter looks almost empty. The fuel level in the filter rises when the fuel tries to find a cleaner section of the filter element to flow through, it starts out at the bottom. As the bottom section gets dirty, the flow resistance grows, and fuel starts building up in the filter, until it finds a cleaner path to flow through. This assuming the filter is installed correctly in an upright orientation.

2. a cheap rotary pump will/should work. The stock carb runs on fairly low pressure, a regulator would be a good idea but you can try without first.

My thoughts on your questions:

1. Yes you can block off the heat riser to gain a tiny bit of HP keeping the intake manifold colder but I will not recommend doing this in cold climate areas. You might lose some mpg though! AFAIK Hot to Hotroad VWs said that! BTW I have never done this, but you can try it and report back! ;-)

1. I usually see the fuel filters on the pressure side of the fuel pump, either electric or mechanical. You never want to starve the fuel pumps which makes them work too hard! The fuel pumps usually work better at pressurizing than sucking fuel. ;-) Sometimes you can tap on the clear fuel filters and get some more air bubbles out. AND Diesel systems don't count! lol I usually see the filters BEFORE the diesel pumps since you never want those pumps to get water or dirt in them. I have seen strainers in front of some electric fuel pumps on Fuel Injected vehicles to stop the larger particles but I have seen "neglected" fuel filters under the gas tanks of the Type 1s! Type 1 gas tanks usually have strainers before the fuel outlet!

**** Oh let me correct myself, before someone else does........I have seen plastic fuel filters in front of fuel injected Type 1s, the Type 4s, and some Porsches, but usually they are all just below the fuel tanks including the electric fuel pumps.

1. The mechanical pump works fine for a stock setup AND is quiet compared to most electric pumps. ALSO the electric pumps don't suck fuel well so the optimal location is under the Bug's fuel tank which requires, for safety, you to set it up so the fuel pump only runs when the starter is operating or there is oil pressure. You would not want the fuel pump to keep pumping out fuel if the engine dies out and the fuel lines are ruptured in an accident!

8^o I agree that a regulator is a good idea since some electric pumps (for carbs) can possibly push out more than 12 psi which is way too much for the stock Bug system.

I vote you repair the stock system and keep it stock! :-)

JMHO

Thank you for your input previously. If I could, I would like to ask you a few more questions about the car. The bug sat for about 6 months without a gas tank or engine. Could the fuel line be rusted inside restricting the gas? The car will start and run a few minutes and then die. This has been a continuous problem even after 3 so called experts have worked on it and we still have the same problem. The last guy put the electric fuel pump on it. We are going to take your suggestion and put the mechanical pump back on it, but it did the same thing with both fuel pumps. Do you know where we can get a new fuel line and the screen that goes in the gas tank? Thank you

troubleshoot why no gas makes it to the engine! clogged strainer inside of the gas tank can be removed! the gas line should be checked for rust and blockage. not sure if you could rod it out, but I would try on mine if no fluid travels through it!

thanks for letting us know why you "were" contemplating an electric fuel pump! ;-)
