Fuel pump install


Homer

Recommended Posts

Planning on installing my shiny new Walbro pump tomorrow, but I'm unsure how to get one of the fittings off.

 

Could anyone tell me how to get the little item circled detaches from the assembly? It looked like its just a bolt but it just didn't seem to want to move :conf:

 

Though it best to ask here before I break something!

 

Also, are there any things I should be wary of? (Already know about staggering the wires and of course, not smoking :p )

It's a union bolt (at least I think that's what they're called). Just undo it like a regualr bolt, it's tight though.

Then take off the fuel pipes and the huge jubilee clip, then unscrew that big plastic ring. That's the most difficult bit, I had to beat it round with a socket extension and a hammer.

leave the car for about 20 minutes after switching the engine off as they hold the pressure for quite a while, this should avoid spillage, when re-fitting the big plastic ring put some silicone grease on it or washing up liquid (anything non petroleum based) it should then p**s on rather than having to knock s**t out of it all the way round, and be carefull with it being plastic it is easy to cross thread, i seem to remember having to do a bit of bending of the metal bracket that holds the pump as it did'nt line up

Sound advice here but don't grolly the thing on with said lubricant applied cos over time that lubricant will work its way out and any subsequent removals will be thwarted cos you tightened it too much. In fact don't use washing up liquid cos that in itself turns into a gluey substance over time. A bit of the old vaseline should be a better idea if you experience tightening problems.

PS that plastic ring nut thingy that holds the fuel tank top in will be the hardest thing to undo. I had to muller the crap out of mine with a hammer and drift to get it to undo.

Thanks to all for the help guys, the pump went in fine today. That plastic ring thingy sure is a bugger to get off!

 

...and no more poping noises at WOT anymore!

what way did you wire the pump up.

 

theres supposed to be a few ways you can do it.

 

does anyone have a pic of what all the pipes are for

which is fuel output to injector rail. which is fuel return line

I got mine from Terry so not sure if they're the same...

 

The kit had:

- pump & filter & retainer

- 2x butt splices

- wiring harness

- fuel pipe

- 2x jubeliee clips

- isolator

 

The splices were certainly part of the pack, think this kit came from the states originally...
