Fuel Pumps ,Filters and fuel lines
« on: May 22, 2010, 09:55:56 AM »
Because of the limited space under the fuel tank, I'm looking for ideas and options and imput for mounting an electric pump and filter. I'm also looking at running a new (larger) fuel line either through the pan or around the outside.
I noticed in another post that 32vsnake has run his fuel line on the outside of the pan.
On page 56 of the June 2010 hot vws, it looks like he has a mount that is attached to the front beam. There seems to be a fair bit of room in that area.
Any idaes would be helpful, even better with pictures.
Cheers

There's plenty of room on the right side of the frame head, opposite of where the master cylinder is.

Put the fuel line inside the tunnel, it's a 15 min job once you've got access.

Is the stock fuel line only supported where it enters and exits the pan? Or does it run through some kind of bracket inside the pan? 15 mins? I'll be poking holes in the ceiling of my garage, the body is mounted on the pan.

It runs through a guide, here are some good pictures.

It doesn't matter how the stock line is supported, you're not going to use it are you?
Cut it off inside the frame head, and by the shift coupler.  Then install a new line beside it, using the stock exit locations.
As I said earlier, it took me less than 15 min to install a new line in a car with the body on.  Here's what I did:

Remove:
all cover plates up front.  Frame head, body by the bottom of the spare tire, front apron/hood latch
the shifter
one seat
the back cover by the coupler
the left rear wheel.

I took the cage off my trouble light so I could stick the whole thing in the tunnel at the back.
From the front, feed the line in, making sure you pass below the cross brace at the pedals.  You need to keep watching so you don't get caught up in all the tubes in there.  Once you get to the coupler, insert a piece of welding rod into the left frame horn at the fuel line's exit hole until it comes out at the coupler.  Put the end of the welding rod inside the fuel line.  Now continue feeding the fuel line until it comes to the exit hole.  Some wiggling of the welding rod may be needed to get it out.  Once you get it through, cut it off at the front, then put whatever bend in the line you want so it will exit the hole at the front.  Do this outside the pan, then put it in the pan with the line going out the grommet.  You may want to put a dog leg bend in the line at the rear too.
Once you've got it all in, you should secure it.  I used really long nylon zip straps to tie the line to any other lines in the tunnel, including the stock fuel line you left in there.  Using long hemostats, I was able to insert the straps and wrap them around the tubes, then pull the end out of the tunnel.  With both ends of the strap out of the tunnel, it's easy to zip them up.

Ok
So now that we have the fuel line figured out, what about pumps and filters. Anyone better or worse that the other???

Whatever you do, stay away from any Holley product.  You'll need your BCAA membership fully up to date if you do.

I recommend the CB rotary pump, and no regulator.  If you use a pump that doesn't need a regulator, the regulator can't fail and leave you stranded.  Take the time to mount it on rubber isolators.

I also recommend running with NO fuel filter.  Again, it's another item that can leave you stranded.  I have never had a filter in my yellow car, and never had any of the problems people seem to try to solve by putting a filter in.  VW never put a filter in your car when it was new, so why do you want one now?  I have one friend with a totally stock 71 Super.  When I first saw the car, it had one of those stupid 99

I gotta disagree here Bruce, all OG VW mechanical fuel pumps had a removeable screen in them. I do agree that the CB pump is the only way to go, quiet and consistant pressure, awesome unit. BTW all those rotary pumps call for a filter upstream of them or the warranty is void.

Its true, the VW pump had a screen in it.  Most of our carbs have such a screen on the inlets (Weber, Dellorto) too.  I never check mine.  Any time the engine comes out, there's never anything in them.

VW also put a screen on the tube inside the tank.  That should be good enough for the CB pump's warranty.

Ok
So we know stay away from holley, put the line inside the pan (with directions), no filters (new tank screen) should work. What size steel fuel line in the pan? -6?-4? I have a -6 an fitting on the bottom of the 56 tank now.

3/8 hardline will do the trick. Run aluminum cause it will be easier to shape/bend.
