upon replacing two fuel pumps in Fish Butt..a VW my brother owns..long story..check the BABE rally thread..

anyways...upon removing the external pump...broke 3 bolts....

so...i was digging in the garage...and found a thick piece of metal strapping..i mean think...like hammer to bend thick.

and i ended up fabricating a pressure clip using the metal strap and using the cross members to secure it on each side...

damn thing nearly took my finger off when it snapped into place..

 
god i hate working on vw's. why the hell cant they get the car to run on just ONE fuel pump? seriously?

 
what i dont understand is why they felt the need to leave the external pump and reservoir fully exposed like that..

makes me think of all the Vw's i see rallycrossing.

 
...protecting exactly that kind of ding-dong engineering from undercar abuse is what rally prep is all about.

;D I like this thread. Try to remember VW got all the left overs the real German engineers didn't want. haha I'm fighting with my fuel pumps too. The VW tards tried to evolve their mechanical injection into their electronic injection and the mk2 chassis were the bastartd children.

Subarus still use two pumps, Saturns use two pumps in their SUV, as do many others. But, that's because of the saddlebag gas tanks. There is no reason why VW needs two pumps for a single flat gas tanks.

Would it be easier to just install a GM type 35psi electric fuel pump into the gas tank? Who knows, but I'm thinking long and hard about it.

 
that leads me into my next question...COULD i install a higher volume pump in the tank and remove the external reservoir?

as i would have to run the return fuel line back to the tank instead of theresrvoir...but doesn't it already do that? im a noob to VW....i should get a book for this..

 
my bet is that the picky ass vw motor wouldnt run if it didnt have exactly what it is supposed to have for fueling. just a guess though.

 
Get a Bentley Manual from germanautoparts.com. I'm new to this backwards engineering too. My 2.oL seems way simpler than my 1.8L. It seems the older they are the more complex they made them.

an adjustable fuel pressure regulator is the key.

whats the point of a higher flowing pump if the car doesn't come with forced induction?

the point of a higher flow pump would be to keep constant pressure at the rail instead of using both the internal pump and the fuel reservoir.

 
okaaaaaaay, wouldnt a simple inline FPR achieve that? im pretty sure a beefier pump will just make you run richer... and richer a/f ratio=ftl with n/a's.

and whats the cost/performance-gain ratio here?

 
yes we would have to run a better fpr and do all the other crap too but its amoot point because we fixed it cheif...hey get on AIM once in a while man..

any word from Ben?

 
We're still talking 'bout older VWs...the ones with the accumulators, 2 fuel pumps, fuel resevoir, ect ect. He's talking 'bout ixnaying the whole shaBang for one pump, one manual pressure regulator, one feed line, and a return line.

If one were to buy the whole system thru Summit including all new fuel lines it would be cheaper than babysitting the current out of date over priced(to replace) old 1980s VW system.

I fixed my cabby leak, maybe, hopefully, what a peice of work!! ;D I made a "U" from 3/8" pipe by heating it with the propane, polish engineered some rubber fuel line, connected the fuel pump to the yellow thingy above it and PRESTO! I haven't tried it yet. Its still in the basement, might be stuck there forever because the kid drove the car into the garage door!
