Summit® mechanical fuel pumps are affordable pumps that deliver superior flow. They are available in two versions; one has 1/4 in. NPT inlets and outlets, provides 5.7 to 8 psi, and can free-flow 80 gph. That's twice what a normal pump delivers. The other has 3/8 in. NPT ports, delivers 6.5 to 8 psi, and can free-flow a hefty 110 gph. These pumps are plated with a bright finish for good looks and corrosion resistance, and the lower housings of both can be rotated through 360 degrees, to make fitting them into tight places a snap.

Q:

Will this work for a 150 shot nitrous system on a sbc? I bought a Holley Blue vane type fuel pump and it's obnoxiously loud,I can't stand the noise.People are looking like "what the heck is that noise??"

Asked by JOSEPH on October 04, 2017

A:

I think a Summit Racing Mechanical Fuel Pump could solve your noise problem, this Pump is rated at 110 gph at 8psi. I replaced a Electric Pump with a Summit Racing Mechanical Fuel Pump SUM25002-1. Into my 300HP SBC and it works straight out of the box. DENIS

Q:

How much pressure are guys seeing with these pumps? Ive got a fairly mellow 350 that runs up the 5,800 RPM, or so. I've got an Edelbrock 1406 600 cfm carb. They are too keen on high duel pressure. Are guys running these without regulators, or actually seeing the advertised pressure and need fuel pressure regulators?

Asked by NIKOLAS on January 16, 2018

A:

Thank you for your question. The Summit 250020-1 Mechanical Fuel Pump is designed to have a maximum pressure of 8 psi.

Q:

I just installed the above pump (110gph) to my summit 8600 VS carburetor and am having backfire issues and won't idle. This pump is rated at 8psi whereas the carb material said not to use greater than 7psi pump. Could this be my problem? If so would raising the primary float level correct?

Asked by THOMAS on January 16, 2017

A:

You may want to check and see if you have a vented fuel cap. Could possibly be starving the engine for gas. Fuel can’t get out of the tank properly without a vented cap.

Caution when assembling the pump!

Summit RacingSummit Racing Verified Purchase

SUM-250020-1
I think this is a great pump for the price, however I had my first one fail after about 200 miles due to what I believe to be incorrect assembly on my part due to there being no instructions. After some investigating, I believe that it failed as I assembled it without the pump in the 'full stroked' position. There was no instructions with the pump, so I just rotated the pump and put the screws back in. However the Edelbrock version of this pump explains in the instructions that the pump must be compressed before tightening the bolts or the diaphragm may fail: "Before fully tightening these screws, the rocker arm must be actuated to and held in the “full stroke” position. This is done to ensure that the diaphragm will be pulled to and held in its maximum working (flexed) position while the retaining screws are torqued tight (25-30 in/lbs.). This procedure will ensure against premature diaphragm wear and subsequent failure due to over-stretching of the diaphragm material when in the full stroke position. Another by-product of an improperly set diaphragm is erratic fuel flow and pressure." ...read more

It's a Fuel Pump

I purchased 3/8 fitting pump. Works perfect out of the box. Had to index bottom bowl to get fitting away from frame rail on '79 Camaro. Easy fix, 8 screws. It comes with no fittings and is 3/8 NPT thread. I would suggest purchasing hose barbs.

Appearance is decieving. not the best looking pump but easily meets all fuel demands in 7000 RPM 440 HP circle track application. If budget plays a roll definitely the one to choose

The pump worked well. On the dyno, my 383 went north of 600 hp with no fuel problems. Should do well in the quarter.

I have replaced the OEM pump with this one and so far it is great. I was experiencing loss of power once in a while. It was really strange and it only did it once in while. Usually under a load and then it was getting worse fast... I think the OEM pump (which was not even 2 years old) had an issue anyhow. I bought this one a few months ago and had it on the shelf. I went ahead and changed it when things got even worse and the engine was not running well at all. I was pretty sure I had fuel delivery issue. It acted like it acts when I am running out of gas, but it does it when there is a full tank. I have noticed a difference in the engine since I installed this pump. Good solid power now and seems very responsive as it should be. I have a fairly stock set up in a 78 K10 truck 4x4. I pull some trailers and it is a daily driver. 9.11-1 compression and a EDL-2102 Camshaft with Factory 882 heads 1.94/1.5 valves. I have a 600 CFM Edelbrock carb with a EDL Performer EPS intake. I had to remove the screws and rotate the pump so the fittings would be in a good spot. The screws are VERY tight and you must make them VERY tight after you rotate to fit your application. I used the fittings SUM-220184B x2. I used yellow teflon tape (recommended for natural gas or propane). It works great and seals no problem. No leaks when I was done. I ran flexible rubber fuel hose from the pump to the carb and a filter, no problems! Use new clamps and make sure they are tight. I am upgrading heads which will increase compression and increase the air/fuel flow. Bigger valves and smaller chambered aluminum heads. I am also upgrading the camshaft when I change the heads. I believe this fuel pump with not have a problem keeping up. I have not tested the pressure to see how much I have now. I may try a small nitrous kit later and I think this fuel pump should work for that as well. ...read more
