fuel pump question

[SupraBro]

Hey guys, so me and my friend picked up a 87 turbo a couple of days ago for a dd. And one thing that is bothering me is that the people before us did the fuel pump mod on a factory fuel pump. I saw it and asked them if it had a walbro in it and they said it was the factory one:yikes: The resistor and relay are missing. Is this something i should be worried about? Should i just see if it last?

Thanks for any info

for a 24 year old pump i would be a little worried ahah

The funny part is he said it was a year old pump..lol

The motor is stock other then 3in dp and hardpipes

Drop the tank and check it out... if not just put the walbro in.. I found another company on ebay making similar pumps a little cheaper with a lot less noise.. haven't used one yet though

 

[SupraBro]

Is it ok to use the walbro on a stock fuel system? Might be awhile before he does any mods.

Your fuel pressure will still be regulated via the stock FPR, so I would think the pump wouldn't hurt anything if you upgraded. Just remember, fuel is one of the few parts that going cheap on can bite you in the long run.

They list their stuff on ebay... but it looks like solid stuff...

There have been a number of counterfeit Walboro pumps end up on Ebay over the years, always best to get parts vital to engine operation from a reputable and well known source. Is possibly leaning out and frying an engine due to a Chinese made knockoff fuel pump worth saving $40? Not a chance I'd take, but to each their own...

Ditto. I'd buy the pump from a reliable source. The Mk4 Denso pump is probably worth it, too. Drop-in, plug 'n play fitment too. Reliability is a good thing in the fuel system!

As for using it on the stock system, it certainly won't hurt anything.

Thats good to know!! Thanks for the info guys! My swap is not happening until two months but i would like to go ahead and get the denso pump in along with other stuff i will need

 

[gwumpkus]

thanx for some good comments! are there variations of the stock Mk 4 Denso pump mentioned? or all years will fit? i'm thinking my fuel pump is already audibly noisy... looks like its "time"...

Anyone know the stock Pressure on the 7mgte? What kind of pressure should i need to run the lexus MAf and 550's and around .75 bar?
