Mech fuel pumps for clevo

I decided to go for a mechanical type fuel pump like the stock one as Ive read to many horror stories on this forum about electric pumps! Any one know of a good one with 3/8 connections that will perform?

Re: Mech fuel pumps for clevo

Electric pumps just takes a little thinking to get a good tank pickup and gravity feed and away you go. I don't recall any horror stories - just do it right.

Holley used to make an aftermarket high volume mechanical pump for the clevo, but they aren't made anymore. So you may be stuck with a new stocko one.

Re: Mech fuel pumps for clevo

I agree that a electric pump, with correct accessories will definately out perform any mech pump. Build into your fuel system a surge tank and at least a regulator and you should have no dramas. I've use elec pumps on most of my vehicles before i went to gas, and after the initial teething probs have all been fine. When you change something be prepared to take a little time for R&D to make it all work.

Yeh thanks mallory are ok quality! Will it maintain pressure with launchs?
Nice ET by the way! What cam and rear gears are you running?


The dramas running an elect pump I figure would be:
The wiring, fuse and mounting it under the car. where?
Noise as mentioned by others.
What to do to switch it off in the event of rollover or accident.
They dont seem to last long.
Overkill for street/strip use.
$ to what gains factor!

Thou as stated correctly engineered it would run OK.

Wiring goes into the car and pops out a hole in your boot close to the fuel pump. You can use the same hole as the fuel sender or just drill a small hole and fit a rubber grommet like I did.

Rubber mount it. Problem solved and you won't look back.

Electronic gas gut off switch. It attaches to the tacho wire. If it doesn't sense a tach signal it won't turn the pump on. It looks like a relay and cost about $20. I've had one for years.

I've had mine on the car 4 years now. Street use and strip.

If it stops you running lean? It would You can save whatever it cost to build an engine. So $1000-$40,000. I'd rather had an elec pump than have no engine.

Running it all is trial and error. A made of mine got away with just shoving an elec pump in and using the stock 5/16" lines and stock tank. Me? Tried 5/16", 3/8" and ended up with 1/2". Couldn't stick with the stock tank either. Just wouldn't flow. Shits me when a mates worked flawlessly.

Brenx please do not think I am being a smarty.

Wiring is a pain to do properly; ie in cabin with gas safety switch/relay/fuse. The holley blue I installed is rubber mounted and the cabin noise is very anoying indeed. It seems to pulse/vibrate the feed line from the tank.

If a suitable mechanical pump was/is available I would use it over an electrical; assuming the correct requirements are met (I have seen BG mechanical pumps on SBC speedway cars).

Im with Jet711 ive got one on an f246/4v/750dp and it hasnt had any problem keeping up yet!

Other than a bit of fuel weeping (not enough to stress about) its fine and as a bonus there rebuildable!

You put up a good arguement but surely a 1/2 line and elec pump are over the top for even your requirements?
In the event of the elec pump failing (which is much more likely with all that wiring, filters, relays etc) the said engine would lean out and you would have a little china syndrome happening too.
