I assume that the 300GE and 500GE both have it located under the dash on the driver's side? I believe there is a fuse box there? Thanks again in advance. | ||

Otherwise there is a problem with the pump Relay PIN layout: 31: Ground 15: 12V from the contact 87: Pump 50: 12V from the starter 30: Always 12V 87v: used on models with a second fuel pump ... i think

Then remove the two screws that hold the fuse panel frame to the bottom of the dashboard, and that will expose the relays behind there. You'll easily see it per David's photo above. If you do need to replace this fuel pump relay, which is shared with other Benz models (cars) of the era, be sure NOT to buy an aftermarket part. Use the factory MB part, which will be of the best quality. For a 500GE, your FPR part number is going to be: 003 545 25 05 It is shared with common US (and world) models such as the 560SEC, 560SEL, 420SEL, and so forth. The current MB list price for this FPR is $33.50 -- WOW, it looks like MB dropped the price of this relay from $78 on January 1st. You are a very lucky guy. You can buy this relay from Tom Hanson at the MB Classic Center, or from MB Asheville for $25 + shipping. http://www.oediscountparts.com/parts/index.cfm?make=Mercedes-Benz&y... You can get aftermarket parts from Kaehler or UROparts via AutohausAZ.com for $67 and $29, respectively. These are both JUNK and NOT worth buying. It doesn't look like these aftermarket brands have caught up to the MB pricing. I hope this helps. Cheers, Gerry | ||

This "NLA" status is often presaged by a dramatic drop in price, as has happened here. We have seen this with numerous other parts over the years, where NLA status is accompanied by a dramatic price drop. The MB Classic parts site already shows this relay as being NLA: http://partssearch.mercedes-benz-classic.com/parts/A0035452505 We'll know more in the coming days. The good thing is that these relays are quite common in other cars, so can be had at wrecking yards and as I mentioned on the aftermarket as a last resort. The list price for the six-cylinder relays (003 545 24 05) as shown above is $276, and they shown as still being available. Cheers, Gerry | ||

For my 560SEC, it's easier just to stock a few spares from cars from the wrecking yard, along with the one new/unused unit that I bought about 5 years ago from the dealer. I actually did have my original unit die about 5 years ago. | ||

I am betting that it will be back available within 24 months. | ||

What would it take? Open it and re-do the solder on the board? I bought a used OEM one in great shape to keep in glove box as a spare so I do not have to mess with 'jumper cable 10 AWG to the pins' solution in an emergency. Would like to have a used one refurbished. There are none in Austria at the factory either. Edited by H1LM002G55 5/11/2017 1:08 AM | ||

They warranty these items that they rebuild, too. Highly recommend you get a Felo screwdriver for the two philips screws holding the under dash panel in place. | ||
