Fuel Pump Pulsator - help needed

[Steve_P]

I'm replacing a dead fuel pump, does anyone know if I need to keep the pulsator (mounted just about the fuel pumps outlet), or
reconnect directly the output of the pump to the metal fuel pipe using the supplied rubber hose and jubilee clips?

I read somewhere that the original pulsator should be discarded?

Any advice appreciated - many thanks, Steve

The pulsator is there to cut down the noise of the pump as it pulses to maintain the 3 Bar pressure. There is no good reason to remove it and ledd good reasons to leave it out. If you broke it, you can get one off eBay or Amazon or Rock Auto to mention a few sources. Are you sure you got a 3 Bar pump?

Hello Steve,

Please let me know what pump you used (brand, type, price, where to buy)
As we are looking for one as well!

I can't help you with the pulsator though...
Where did you read this?


Good luck!

The pump was used in a lot of GM products back in the day. It is a 3 Bar pressure and has a lot of aftermarket replacement part numbers.

The original GM/Delco pump is no longer being made, so you will need to get one of the replacements.

I bought a few different versions and ended up installing this one: http://www.ebay.com/itm/400205704860#ht_2108wt_1162

The most common model GM car that used it was the 1993 Buick Riviera.

The pulsator is available from several eBay sellers: http://www.ebay.com/itm/380539337334
The mounting triangle (above the pump) is http://www.ebay.com/itm/200758754920 Rock Auto calls it a mounting kit.

Rock Auto has all of the parts you will need listed under 1993 Buick Riviera, Fuel/Air.

The pump kits come with strainer and the lower mounting washer/grommet.

I used a different strainer from the one supplied as it was too long. Under Rock Auto's Buick listing they show a shorter, flat and oval strainer for a couple of dollars. That is a good choice as it fits in the well of the gas tank. The FSxxx and STxxx numbers are generic and can be searched to find alternate suppliers if needed.

The Rock Auto fuel pump kit from PERFORMANCE ELECTRIC, Part # P240KC looks to have the correct strainer in the kit but don't be suprised if the filter is different than that in the picture. Just make sure it will fit inside the well in the tank.

You will need to splice a new connector (supplied with the kit) to the existing wiring. The two fat sections in the original wiring are chokes (they filter out electrical pulses for the EFI) and should stay in the circuit, so splice below them.

I replaced my pump, mounting grommet, pulsator, mounting triangle and strainer for less than $40.00. The fuel filter was installed backwards when I went to replace it so watch the flow direction and make sure you point it in the right direction.

If you need any other info, there are several write-ups on LEC and I did a review at viewtopic.php?f=46&t=15509#p277635

Great, thanks for the feedback guys

The pump I found was cross referenced to the AC delco part number and comes from a company called Hi part number P3015.1.

I purchased mine from Merlin Motorsport: www.merlinmotorsport.co.uk/advanced_search_result.php?keywords=lotus+elan+fuel+pump

There also appear to be some available cheaper on ebay, I'm always a bit wary about buying safety critical parts directly off ebay! So the price spreads the £40-£60 range.

Hi are also distributed by Glencoe www.glencoeltd.co.uk/who look to have a good reputation and supply aviation parts, so although I've not heard of Hi they appear to be a reputable brand - time will tell!

There were no instructions supplied with the pump but I found these instructions HERE and noted in Section C that the pulsator may be discarded for rubber pipe, which was supplied with the pump - hence my original question. However I will leave the original pulsator in place as it looks to be ok.

Thanks again, Steve
